Specific heat capacity is the amount of heat required to raise the
temperature of a particular substance of mass (kilogram, gram, pound)
by 1 degree (celsius, fahrenheit, kelvin).
The specific heat capacity of a substance, chemical compound, or molecule, is a measure of the amount of heat energy necessary to increase the temperature of a unit quantity of that substance by a given temperature interval.
Q = mcΔT
Q is taken to be the heat energy put into a certain amount of a substance with mass m,
c is the specific heat of the substance, and
ΔT is the temperature change.
