Question

How could latent heat be explained from the graph? Explain in detail

Answer 1

In order to initiate a phase change and complete it, some energy in the form of heat is required. this heat is called latent heat . thus all the energy supplied during this phase will be utilized only for phase change process and not for increasing the temperature.. thus during the release of latent heat the temperature remains constant

Answer 2

Latent heat can be understood as heat energy in hidden form which is supplied or extracted to change the state of a substance without changing its temperature. ... Black used the term in the context of calorimetry where a heat transfer caused a volume change in a body while its temperature was constant.
