These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules. "If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. The example we will use here is ice melting into water
the temperature of a substance while changing often times while rise or fall depending on what is happening. Say you have an ice cube and you put it into a hot soup to cool the soup down the ice cube melts due to the surrounding temperature. In other cases if you want to cool something hot like say hot water you can 1:put it in a cool place such as a refrigerator or freezer or 2:you can leave it out to cool to room temperature.
