(3 ).Regarding heat capacity, latent heat and temperature: (a ).The difference between specific heat capacity and heat capacity relates to the mass of substance involved. (b ).Heat is a form of kinetic energy which can be transferred from a colder substance to a hotter substance. (c ).Temperature is the property of a substance that determines whether an object will receive heat or give heat to another object. (d ).An example of latent heat of fusion is the heat associated with a solid dissolving into a liquid at a constant temperature. (e ).A clinical example of latent heat is in the use of ethyl chloride spray for topical anaesthesia.
