Latent heat is the heat required to convert a solid into a liquid or vapour, or a liquid into a vapour, without change of temperature.That is why there is no rise in temprature, as all energy applied is consumed in conversion of states. When something changes phase from solid to liquid, or from liquid to gas, it takes energy to break the intermolecular interactions. so the temperature stays constant.

Physical changes involve changing the physical properties of a substance. Some examples of physical properties include color, volume, shape, and phase changes.
For example, you can take a flat, smooth sheet of paper and crumple it into a ball or fold it into an airplane. While it may look very different in these three forms, it is still paper.
A change like this, which alters a substance's appearance without changing its chemical composition, is known as a physical change.
