WebThe specific heat (also called specific heat capacity) is the amount of heat required to change a unit mass (or unit quantity, such as mole) of a substance by one degree in … In thermodynamics, the specific heat capacity (symbol c) of a substance is the heat capacity of a sample of the substance divided by the mass of the sample, also sometimes referred to as massic heat capacity. Informally, it is the amount of heat that must be added to one unit of mass of the substance in order to cause an increase of one unit in temperature. The SI unit of specific heat capacity is joule per kelvin per kilogram, J⋅kg ⋅K . For example, the heat required to raise the temp…
WebDifference between Heat and Temperature. Following is the table explaining heat vs temperature: Parameter. Heat. Temperature. Definition. Heat is defined as the total energy of an object that has molecular motion inside it. Temperature is defined as the measure of the thermal energy of an object.
