Why is the temperature hot into a dog at 30 ° C, and the bath water is frozen into a monkey at 30 ° C?

Q

How much can the maximum temperature of water be?

A

You may talk out: 100 ° C! That's right, this is how the degree Celsius is defined, but don't forget that there is a premise, that is, it must be pressed at the atmosphere. On the low -pressure Qinghai -Tibet Plateau, the water can be boiled to 80 ° C; in a high -pressure high -pressure cooker, the water can be burned to more than two hundred ° C and it is still not boiled, so the high -pressure cooker can cook the rice faster. However, there is a limit to increase the boiling point. When the water temperature reaches 374 ° C, no matter how pressurizing the water, it will boil into water vapor. This is called the critical temperature of water. In other words, the highest temperature of the water is 374 ° C, and the temperature becomes water vapor.
