reggie puts a breaker of ice and water on a hot plate he observes the ice slowly melt as shown in diagram below after a few minutes only liquid water is left in the breaker eventually the water become hot enough to boil the liquid water changes to water vapor to a gas

during this process, energy is absorbed by the water molecules to break the bonds between them and form water vapor. This energy, known as latent heat, is what causes the water to boil and evaporate. At this point, the water molecules are no longer held together as a liquid but instead spread out and move freely in the air as a gas.
