La cantidad de calor necesaria para aumentar en un grado la temperatura de una unidad de masa de una sustancia se conoce como calor específico. Si el calentamiento se produce manteniendo constante el volumen de la sustancia o su presión, se habla de calor específico a volumen constante o a presión constante.

En todas las sustancias, el primero siempre es menor o igual que el segundo. El calor específico del agua a 15 ° C es de 4.185,5 julios por kilogramo y grado Celsius. En el caso del agua y de otras sustancias prácticamente incompresibles, no es necesario distinguir entre los calores específicos a volumen constante y presión constante ya que son aproximadamente iguales. Generalmente, los dos calores específicos de una sustancia dependen de la temperatura.
