BBC photographer crying in Antarctica, is it really that hot?

Rising temperatures in Antarctica are real, but they don't make people cry. The videographer cried because he saw the melting of the Antarctic glaciers and the homelessness of many poor animals, and he was saddened by the deterioration of the environment.

It's really hot over there in Antarctica, all the glaciers have melted, and it's much warmer than usual, all the penguins are on shore, and the ice that used to be very strong has become like water.

In fact, the reason why the photographer cried was not because it was very hot, but mainly because the climate was constantly warming, and this place had become the only pure land, and he was also crying for this pure land.

Because they weep for the sake of human beings and animals. Animals have lost their food and homes. They walked around pitifully, dying, and they felt particularly helpless.

Now that the whole world is warming, this summer will definitely be hot in Antarctica. Polar daylight often occurs at the South Pole, and the sun appears 24 hours a day at the extreme, so you can imagine that temperature.

No way, Fuzhou is a basin, surrounded by mountains on three sides and facing the sea, the subtropical high pressure will send heat to Fujian in summer, and the geographical conditions of Fuzhou cause the heat to not dissipate, the same is true in winter, cold will be cold for a long time, and hot in summer for a long time.

It's not hot yet, it can reach more than 40 degrees, and more than 42 degrees is considered normal.

The advertisement on Chongqing TV station stated that it was a 7-day refund without reason, but from January 11th to now January 21st, the customer service has not been contacted for a refund, and in the products received, there is no mention of which company is the merchant sold by Suhot Xiaobawang. Only the following payment voucher is available, and the contact person cannot be found online.

Unscrupulous merchants are only enthusiastic when selling goods, and no one pays attention to them after sale, and their attitude is 360 degrees. And from TV shopping to receiving the goods, I don't know which company sells the product when I ask customer service later.

Chongqing TV does not have any audit control over TV advertisements, and the effect that consumers see on TV shopping is exaggerated advertising, and the promised after-sales service is nonsense. It is only for the purpose of selling goods, and does not provide after-sales service. So far, there are many consumers on the Internet who are like me, who have bought products after seeing TV shopping, and everyone has been deceived.

However, everyone is experiencing the same problem as me, there is no way to complain, no way to refund. But at present, there are still hot sales on search engines and TV commercials, and they are different, ranging from 100 to 199, each of which is said to be the only designated sales channel for TV shopping.

I hope you will be cautious when you buy after seeing this message, the actual effect is not as stated in TV shopping, and there is no after-sales service. I hope you will be cautious and cautious. Unscrupulous merchants will have retribution!!

It's not as good as TV says, my room is only 15 square meters, and there is no heat in the room for four or five hours, according to what TV says is suitable for 23 square meters, I really want to return, it's better to pay dozens of dollars for electric heaters, I hope you can't be fooled, I've been fooled.

I bought one and used it for two days, and the nineteen-square-meter room didn't work at all, not as good as the original air conditioning fan. Because the Speedmaster is too small, it can only be used in a house with five or six square meters. The authenticity of TV shopping advertising products is only 120%, 80% of consumers are misled, and the products are exaggerated.

Fake, don't be fooled, the old man at home watched TV shopping, directly called**bought three, bought it back, it was useless, it was still cool after 24 hours, I couldn't retreat, I went back to ** came back in the past, I heard that I wanted to sell it, and I directly shirked the responsibility, not their company bought it, and then I played more**, and I didn't go back to **, it seems that our number is blacklisted.

Real**,Lie to you and don't negotiate,My dad bought it on TV shopping,It's so good on TV.,What's the use of it?,I want to return.,Result**Can't get through.,Can't get back.,The TV ad says 7 days to return and 15 days to change.,It's all **,Don't go up,

This is a typical deception, when I said I wanted to buy it, I was very enthusiastic and had a good attitude. As a result, I drove in the 3 flat bathrooms for more than 4 hours without any response, and even the temperature next to the 10 cm machine did not change at all. After verification, I didn't answer the ** contact for returns, I hit one in a row, and then I yelled directly:

Stop fighting, I'll get back later. Then I waited for most of the day and didn't see the back**, and then I was busy with the tone. I used someone else's mobile phone to call again, and this time I answered it immediately, and when I heard that it was going to be returned, my attitude immediately changed again, saying that I would contact me after reporting.

As a result, the other end exploded, and he yelled directly: What's wrong with my attitude, what attitude do you want me to use towards you, what attitude do you want me to use. After the roar, he snapped and hung up the **.

If I call again, no one will answer, let alone reply to me after she reports it. It's obvious that it's fraud, and it's one that can deceive one. The TV station doesn't care how effective it is.

Just give money. Anything can be released. I write down my own personal experience and hope that people will not believe it.

Don't go for it. Civilized people don't want to explode foul language. Ha ha.

Deceitful, I just bought one a few days ago, it arrived yesterday, I took it home and tried it for a few hours, the room was not hot, it was not as good as the heat of the hair dryer, and no one answered if I wanted to return the fight, I really don't know how the country allows this kind of false advertising to deceive people on TV every day, don't be fooled again.

Yikes! It's useless, my dad bought 2 on TV, the same as a hair dryer, and I don't give it back, don't buy it.

Broken garbage is not as good as the little sun that costs 20 yuan outside. Look at the quality of workmanship, who buys who is fooled. It's not good to retreat, and I don't pick it up. None of the companies say anything is lying to the elderly.

I just bought one, it's not hot at all, and it breaks after a day of use, I can't contact the after-sales service, no one cares, it's a lie.

Fake, I bought one, no use for fart, pit people.

The law of conservation of energy, if you don't waste electricity, you won't be warm, and you want to change the heating method without using electricity to warm up, like the air conditioner is more power-saving than the heater because the heater is direct heat and the air conditioner is the heat from the heat pump, like Xiaobawang is direct heat, and the hair dryer is a principle, either it costs electricity or it is not warm.

The Bureau of Radio, Film and Television should properly review the authenticity of the advertisement, so that it will know that it does not do anything when it collects money

TV shopping is**yes**, don't be fooled, it's all fake.

Not as good as the TV says.

This thing should be like Leonardo da Vinci's solar-powered flashlight.

Don't trust TV shopping.

My grandma bought one that wasn't good at all, it wasn't hot at all, it was a lie.

The family broke the rice cooker, took out the pot bladder, and plugged it in with a small electric fan, which was warmer than Xiaobawang's.

Just look at its power consumption, which means that the power is not large, and it can be used in winter.

Practice is the only criterion for testing truth. Through the actual insurance, it is proved that the steamed steamed bun is the first to be cooked by the lower layer, that is, the lower layer is cooked first. What if, ideally, the steamer does not absorb heat at all, is not breathable, and does not exchange heat with air?

It may be cooked at the same time. Why does hot gas go up? Because there are more cold air molecules in the lower layer of the hot gas than in the upper layer of cold air, the pressure generated by the collision is greater in the lower layer than in the upper layer, so the hot gas goes up.

But steamed steamed buns, not a separate hot gas, but a continuous hot gas, the cold air in the steamer has long been emptied, negligible, hot gas is like a stream of water, not the hot gas goes up, but must go in the direction of the airway, if the steamer is changed to a curved trachea, the hot gas will still be pushed along the trachea, as if a force pushes the gas to go. If it is not a continuous hot gas, it is just a hot gas, in other words, as soon as the steamer is hot, it is taken down to cool down, it must be that the lower layer is cold first, and the upper layer is cold, because the lower layer enters the cold air first, and the upper layer still has hot air. If the steamed bread is to be cooked at a certain point in time, just take off the whole steamer, under the residual heat, the upper layer may be cooked first, and the lower layer will not be cooked.

I think the experiment done on TV,It does illustrate the problem,But the experiment is still not rigorous enough,This experiment should be added:Let a certain layer put steamed buns,Other layers don't put steamed buns,For example, a total of 5 layers,Then divide into 5 groups,At the same time, experiment,Ensure that the fire below is about the same,Take a look,Which layer is ripe first,Which layer is ripe later。。 Add another experiment:

Place a steamed bun in each layer, and each layer of trowels does not overlap in the top view, to see which layer is cooked first and which layer is cooked.

Why is the bottom layer of steamed steamed buns ripe first, I think the expert's explanation is very reasonable: first.

First, layer by layer endothermy, the gas temperature is getting lower and lower; Second, at the top level, the gas liquefies and releases heat, but not all of this heat is used to heat the steamed buns.

In fact, steamed steamed buns are exactly the same as ordinary heat conduction, close to the heat source, of course, they must be heated first.

This example teaches us that we can't take things for granted.

The physics teacher must have said so, the steamed buns on the upper level are ripe first. Because the vapor goes up after being heated, the volume increases and the density decreases, pushing the cold air downward. So the steamed buns on the upper layer are ripe first.

Physics teachers below high school level must say this, because it is considered in an idealistic situation, and it does not correspond to the actual situation.

However, after considering the internal structure of the steamer, combined with the actual consideration: the heat is transferred layer by layer, the water vapor in the rising process is the first to meet the steamed bread of the lower layer, and the cold liquefaction is exothermic, when the lower layer does not reach a sufficient temperature (close to 100 degrees), the hot gas can not reach the upper layer, and the heat of the upper layer mainly relies on conduction heat transfer, so the heating is very slow, when the bottom layer reaches a sufficient degree, the upper layer begins to heat up rapidly, layer by layer, and so on, so the lower layer heats first.

The teacher's is just to make you aware of some of the properties of gases, not the actual situation.

Above, the star's water vapor and hot air are hot, and the density is smaller than that of cold air, and the hot air runs up and gathers on it, and then it slowly heats up to the bottom Journey to the West, the plot of the steamed Tang monk in Lion's Camel Ridge is wrong, and I was deceived when I was a child.

It's true that the lower layer is hot first, but the first ripe layer is indeed the upper layer... You shouldn't have heard clearly?

To understand whether the upper layer is first or the lower layer is first born.

Steamed bread is steamed by the heat exchange between water vapor and steamed bread; A large amount of water vapor is generated near the heat source; The temperature is always highest near the heat source, and the farther away from the heat source, the lower the temperature.

When steaming steamed bread, due to the presence of most of the water vapor in the steamer, it will rise, and some of it will overflow, and the heat exchange with the steamed bread will be carried out during the rise of water vapor, and the temperature of the steamed bread will increase, and the temperature of the water vapor will decrease (some of the water vapor temperature will become liquefied into water when the temperature decreases); During the rise of water vapor, the temperature becomes lower due to the continuous heat exchange, and the concentration of the liquefaction decreases due to the partial liquefaction, so the upper temperature will also be the lowest.

Coke at zero degrees, Sprite is really sugar-free and calorie-free. As a **person, you can drink, and I really don't have any impression of **fitness. You can drink it with confidence.

But my personal advice is that it's better to drink less. This drink is probably a little bad for the body. No matter how well it blows, it can't change the fact that it's a carbonated drink.

It's just a change of ingredients, and it's not really good for the body. Of course, it's okay to drink this thing, and it won't have a big impact. As long as you don't hold it every day and drink it, there is basically no obvious harm.

However, for the sake of good health, it is better to drink more plain water. Or make some tea is also good.

You can drink it, but the drink definitely has additives and the like, so for the sake of health, let's drink plain water.

It's actually impossible to have no calories, this is just a propaganda technique, maybe there will be less calories in it, and the advertisements should not be easily believed.

There are no zero-degree drinks, and these drinks must have added calories from other aspects, so let's drink plain water.

The sugar content of these drinks is relatively low compared to other drinks. So it's more liked by ** lovers. However, carbon dioxide drinking water is relatively harmful to the body. Do not drink for a long time.

Coke Zero is sugar-free and calorie-free, it doesn't provide any nutrients, just a flavor for consumers, but it's enough to appeal to many fitness people who crave soda.

I think even if it's a zero-degree drink, we shouldn't drink too much, because drinking such a drink is not good for our body. I think we should drink more hot water and drink more plain water.

Personally, I think that zero-degree drinks are really calorie-free, and people can drink them, and it has no effect on our human health, because zero-degree drinks use synthetic sweeteners.

In terms of ingredients, zero-degree drinks basically have no calories, and there is no added sugar in terms of sweetness, but another sweetener is added.
