At 1 standard atmospheric pressure, the boiling points of alcohol and water are 78°C and 100°C, respectively. Place them in two tubes and place them in boiling water under constant heating. Then, the boiling point of the two tubes is ______. At 1 standard atmospheric pressure, the boiling points of alcohol and water are 78°C and 100°C, respectively. Place them in two tubes and place them in boiling water under constant heating. Then, the boiling point in these two tubes is ______.

(1) In the boiling water whose temperature reaches the boiling point of 100°C, the temperature of the water remains unchanged. The water in the test tube absorbs heat from the beaker. After the temperature reaches the boiling point of the water, it can not continue to absorb heat from the beaker as the temperature of the water in the beaker. At this time, although the boiling point of the water reaches 100°C, it can not absorb heat.

(1) In boiling water with a boiling point of 100°C, the temperature of the water remains unchanged. The water in the test tube absorbs heat from the beaker. When the temperature reaches the boiling point of the water, it is the same as the temperature of the water in the beaker. It can not continue to absorb heat from the beaker. At this time, although the boiling point of the water reaches 100°C, it can not absorb heat, so...

Is the boiling point of water 100°C or 99.975°C at standard atmospheric pressure? Remember at the time of learning is to say: the standard atmospheric pressure of water boiling point is 100°C. Since the provisions of why "according to the British journal" Electronics and Radio World "report, from January 1,1990, the boiling point of water will no longer be 100°C. The new boiling point is 99.975°C, standard atmospheric pressure. This is the International Committee for Weights and Measures after the original standard issued the official notice." Baidu encyclopedia also said that the boiling point of water is 99.975°C!

In 1990, a new international temperature scale was introduced, which was very close to the thermodynamic temperature scale, but the new temperature scale was about 0.025°C higher than the old temperature scale, so that the boiling point of water at the new temperature scale became 99.975°C
