First of all, water temperature is the macroscopic reflection of the kinetic energy of water molecules in water. The temperature of the water increases, which means it is obtaining energy from the outside world and converting it into its own internal energy. The energy of water molecules increases. Water molecules are immobile water molecules and water is immobile water. There is no difference. As for whether you can drink it, it mainly depends on your heating method. If harmful substances enter during the heating process, do not drink it.
Does water at 100 degrees absorb heat when it turns to steam at 100 degrees?
1. Can water boil if heated with steam to 100°C?
p> First of all, it can boil
Because steam from water is a gas and will liquefy, it will release a certain amount of heat to keep the water at a constant temperature de 100 degrees Celsius.
If so If the water is placed in 100 degree water, it will not work because it cannot continuously provide thermal energy. Boiling requires continuous absorption of heat. Even if there is heating equipment underneath, the innermost water cannot. to boil. The reason is the same as above
2. There is a problem between your question and the following supplement
Under standard conditions, the boiling point of water is 100 degrees Celsius. When it reaches 100 degrees Celsius, it boils
You said can boiled water boil at 100°C?
The answer is yes
< p>When 100°C Water at -degrees turns into water vapor at 100 degrees, it absorbs heat.The heat of vaporization of water is 40.8 kJ/mol, which is equivalent to 2260 kJ/kg. Generally: The amount of heat needed to evaporate water at its boiling point est five times greater than the amount of heat needed to heat the same amount of water from one degree Celsius to one hundred degrees Celsius.
The heat of vaporization is 2,260 J/g, so when 1 gram of water at 100 degrees turns to water vapor at 100 degrees, it absorbs 2,260 joules
