Quizplus · Accepted Answer

Specific heat is the amount of heat needed to change the temperature of a substance per unit mass. It is a characteristic property of a substance, and different substances have different specific heat values. Sensible heat refers to the heat that is involved in changing the temperature of a substance, while latent heat is the heat involved in changing the phase of a substance (e.g. melting or boiling). Relative heat is not a commonly used term in thermodynamics.
