High heat of vaporization of water
Web1 de abr. de 2024 · Yes, water does have a high heat of vaporization. This is because water molecules are attracted to each other by hydrogen bonds. When water is heated, the molecules move faster and the hydrogen bonds break. This requires a lot of energy, which raises the temperature of the water.
