PHYSICS - Matter - Specific Latent Heat

The video tutorial explains specific latent heat, which is the heat energy involved in changing the state of a substance without changing its temperature. It distinguishes specific latent heat from specific heat capacity and highlights that specific latent heat is unique to each state change, such as from solid to liquid or liquid to gas. The tutorial uses the example of a plastic fork melting to illustrate how heat energy breaks molecular bonds during state changes. It also covers the calculation of specific latent heat using a formula and provides a practice problem to reinforce understanding.

Why does the temperature of a substance remain constant during a state change?

How can a substance have two specific latent heats? Provide an example.
