The same is water, why does cold water taste better than lukewarm water?

Personally, I think that cold water gives people a cold and cold feeling, and warm water will make you feel like you don't want to swallow it when you get to your mouth, so cold water tastes better and more acceptable than warm water.

That's because the temperature of our human body is around 37 degrees, cold water can make us feel better, warm water may be about the same temperature as us, and we don't feel anything.

There is a subtle difference between the taste of hot water and cold water after it is cooled, because after the water is boiled, the ions and oxygen contained are different, so the taste is different.

There are three types of cold water here, the first is that cold water is not the water after the hot water has been cooled, but other water. Second, cold water is water that has been boiled and cooled. The third is that it is boiled in cold water and exposed to air for a relatively long time.

In the first case, the taste of the water is not the same, because the boiled water will contain less substances than the unboiled water, which is the difference between different tastes.

In the second case, the taste of the water is the same, and it is the taste of the water after it has been boiled.

In the third case, the taste of the water will be different, because after being exposed to the air for a long time, the water will melt into the air substance, and the taste will naturally be different.

After the hot water is cooled and the hot water is mixed with cold water, it must be judged according to the above three situations, and cannot be generalized, because the core is the problem of how many substances are contained in the water, which affect our taste and taste. In general, there will always be a difference in taste, after all, the process of hot water cooling is also a process of contact with air, and this process will change more or less slightly, but it may not be able to be felt. In the same way, before the hot water is colded, the substance content in the water is small, so the overall substance content ratio is different from the original cold water, so we have to be cautious and come to the final conclusion that the taste of hot water is still different from that of hot water mixed with cold water, and there will be more or less slight differences.

Does hot water taste the same as hot water mixed with cold water when it is cooled? It's not the same, no matter what the situation is, there will be subtle differences, it's just a matter of big and small differences. The main reason is the difference in the oxygen and ion content of the water, as well as the difference in the microbial content, which is the reason for the different tastes.

The taste varies greatly depending on the quality of the water, some water is sweet when you drink it, and some water is slightly bitter.

It's different, the nutrients are completely different, and the healthier thing is that after the hot water is cooled, there is no particularly serious smell and no microorganisms.

No, the taste of the two types of water is completely absent, and the water of the former is relatively clean; But the water behind it can produce a particularly strong disinfectant smell.

It is different, the material composition is not the same, the nature is different, and hot water mixed with cold water will lead to the breeding of bacteria.

The taste is pretty much the same. There is not much difference, the taste is about the same, and the temperature is about the same.

This is normal.

Tap water is drinking water produced by professional equipment through multiple complex processes. The treatment process of tap water is as follows:

First of all, the water source must be pumped from the rivers and lakes to the water plant (the water intake is different in different regions, and the water source directly affects the quality of drinking water in an area);

Then after coagulation, sedimentation, filtration, sent to the clear water pool and disinfection, the water pump is fed into the tap water pipeline at high pressure, and the main pipeline generally uses prestressed concrete pipes, steel pipes, PE pipes, ductile iron pipes and other pipes;

Eventually, it is shunted to the user's faucet. The whole process has to go through multiple water quality tests, and in some places, it has to go through secondary pressurization and secondary disinfection before entering the user's home.

Of course, there will be a smell of chlorine dioxide (disinfectant powder).

There are two scenarios:

The temperature of the water is 0-4

Celsius. between the times, depending on the water.

Abnormal swelling. Pyrocondensation.

Cold expansion) shows that the higher the temperature of the water, the greater the density. Then the same volume of hot water is more massive than cold water, and the heavier it is.

When the temperature of the water is greater than 4 degrees Celsius, according to.

Thermal expansion and cold contraction. Regularly, the higher the temperature of the water, the less dense it becomes. Then the mass of hot water of the same volume is smaller than that of cold water, and it is lighter than cold water.
