High heat of vaporization and sweating
Web1 de abr. de 2024 · Water has a very high heat of vaporization. This means that it takes a lot of energy to turn water into steam. The heat of vaporization is the amount of energy required to change the state of a substance from a liquid to a gas. For water, this value is 2260 kJ/kg. This means that it takes 2260 kJ of energy to turn 1 kg of water into steam.
