If the same amount of heat flows into (or out of) equal masses of different substances, their temperatures may not change by the same amount. Specific heat capacity (c) tells us how much heat energy is required to change one unit mass of a substance by one unit of temperature. Specific heat is related to heat (q), the mass of the sample (m), and the change in temperature (∆T) by the equation q=cm∆T.
