Can 4 cups of 25 degrees Celsius water be mixed together to become a 100 degree boil

No.

Heat transfer, which is a way of changing the internal energy of an object, is the process by which heat is transferred from a hot object to a low temperature object, or from the hot part of an object to the low part.

The only condition under which heat transfer occurs.

There is a temperature difference, which has nothing to do with the state of the objects or whether the objects are in contact with each other.

Since they are all 25 degrees, the conditions for heat transfer cannot be met. The temperatures don't add up.

For example, if you mix 75 degrees of water and 25 degrees of water, the result will certainly not be 100 degrees. According to the knowledge of heat transfer, heat is transferred from a hot object to a low temperature object, then the water temperature should drop at 75 degrees Celsius, the water temperature should rise at 25 degrees, and theoretically, the final result is 50 degrees.

Mix 4 cups of water at 25 degrees and finally 25 degrees.

Related Introductions. Heat transfer (or heat transfer) is a physical phenomenon in physics, which refers to the transfer of heat energy due to temperature differences. In heat transfer, heat is used to measure the change in the internal energy of an object. There are three main forms of heat transfer: heat conduction.

Thermal radiation and heat convection.

As long as there is a temperature difference within or between objects, heat energy must be transferred from high to low temperature in one or more of the above three ways. For a solid heat source, when the temperature difference between it and the surrounding medium is not very large (about 50°C or less), the heat transferred from the heat source to the surrounding medium can be determined by Newton's cooling law.

to calculate.

No, you can't. The temperature of any mixture of the same water does not change, so four cups of 25 degrees Celsius water are still mixed at 25 degrees Celsius.

Do you think that four glasses of water mixed together are still the same volume of water? If you can compress it to its original volume, it may be more than 100 degrees.

No way. 10 drops of 25 degrees water will burn the floor.

Wow, I'm so scared that I hurriedly drank 4 and was spit out by 25 degrees of water, thank you for the reminder!!

Under ideal conditions (e.g. 1 atmosphere), regardless of the ambient temperature and the specific heat capacity of the container, 100 water (liquid) and 0 water (liquid) are mixed to 50 (liquid).

First consider whether the entropy changes: since the front and back are liquid reactions, the entropy becomes zero.

Then consider the change in the deficit energy (enthalpy), because the specific heat capacity of water is not absorbed by the surrounding environment and the container, so the weighted average is 50

When 100 is water vapor or 0 is ice, the entropy change will be considered, and the results will be high and low, respectively. Considering the surrounding environment and the specific heat capacity of the container, there is heat loss, so the result is low.

In summary, the mixing of water is affected by many factors, and only a rough value can be obtained, which cannot be accurately calculated.

1 liter of water at 100 degrees Celsius is lowered to 50 degrees Celsius and released: 4200 * 1 * (100-50) = 210000J of heat.

1 liter of water at 0 degrees to 50 degrees absorbs: 4200 * 1 * (50-0) = 210000J of heat.

So, without counting heat loss, it's 50 degrees.

If the heat loss is calculated, it will not be 50 degrees.

It is not entirely true that water can only boil at 100 degrees.

The boiling point of water is related to the air pressure, if the air pressure is greater than the standard atmospheric pressure.

Water does not absorb heat, molecules do not move, and even if it is heated to 100 degrees, it does not boil. In general, the air pressure and boiling point are proportional to the bend.

The higher the air pressure, the higher the boiling point, and vice versa. or seep.

At standard atmospheric pressure, the temperature at which water boils is 100 degrees Celsius.

The temperature of water boiling is generally related to the air pressure, the higher the air pressure, the higher the water boiling temperature, the lower the air pressure, and the lower the water boiling temperature. Generally, the boiling point of water is 97 at an altitude of 1000 meters, and the boiling point of water at an altitude of 3000 meters is 91, at an altitude of 8848 kilometers above sea level, Mount Everest.

The boiling point of water is only 72.

There are two things in the world that cannot be simply added, one is the point in time and the point in time (different from the time period), and the other is the temperature (different from the temperature difference), four cups of the same volume of water are mixed together, and the temperature is the average of the four cups of water temperature (25 4) 4 = 25.

Hello! OK! Also, you can go to heaven by stepping on each other with your left foot and right foot! Kiss, am I right?

Summary. Water at 100 degrees Celsius dissipates heat quickly, but when it reaches 50, it will dissipate at the same rate as when it starts to cool down at 50. So it can't be faster than 50's.

A glass of 50 degrees of water and a glass of 100 degrees of water, 100 degrees plus cold water, the degree is not the same as 50 degrees.

Yes. 100 degrees of water is fast to dissipate heat, but when it dissipates heat to 50, it will be as resistant as 50 when it starts to cool down. So it can't be faster than Zhiliang 50's.

The final power is the same.

The same large cup, a full cup of 50 degrees. Half a cup of 100 degrees, half a cup of 100 plus a full cup, is the degree the same?

Regardless of the volume difference (very small) of water at different temperatures, it looks like almost 50.

I'm sure I know pretty much that.

A little higher at 50 degrees or a little higher at 100 degrees with cold water.

100 degrees plus cold water a little warmer.

Are you sure? It's only half a cup of 100 degrees. Add half a glass of cold water, is the temperature a little higher?

Half a cup, hot water is better than cold water heat dissipation block.

It should be 50 degrees Celsius.

If the water at room temperature is 20, it is calculated according to the formula q=cm t, where c= j (kg);

The temperature after mixing is t, and the heat absorbed = the heat released, then: cm1(100-t)=cm2(t-20), m1=m2,100-t=t-20, t=60

If the room temperature is 20°C, the temperature after 1:1 mixing is 60°C
