The specific heat of a substance is the change in heat that is required to change the temperature of a unit mass of a substance by a single unit of temperature. It is expressed in any terms that include heat, amount of the substance and temperature like J/(mol*K) or J/(g*K)
Specific heat is dependent on varies characteristics of a substance and varies over has a wide range. Some of these include the structure of the substance, the forces of attraction between the particles that make up the substance, the dimensions of motion possible for the particles, the presence of impurities, etc.
