Explanation:
Detailed explanation-1: -Latent heat is used to overcome the force of attraction, when we are heating it increases the kinetic energy of the molecules but when we reach the saturation point all that heat is helpful to overcome the force of attraction, then the change of state happens.
Detailed explanation-2: -Matter can change from one state to another when thermal energy is absorbed or released. This change is known as change of state. The graph in Figure 11 shows the changes in temperature as thermal energy is gradually added to a container of ice.
