Question

A quanity of heat required to change the unit mass of a solid substance, from solid state to liquid state, while the temperature remains constant, is known as (A) hoar frost (B) sublimation (C) latent heat (D) latent heat of fusion

Tardigrade Admin · Accepted Answer

Latent heat is defined as the amount of heat required to change the state of a substance, while the temperature remains constant. Here, the state changes from solid to liquid, hence, it is defined as the latent heat of fusion.
