材料的比熱容

Overview

Specific heat capacity ($c$) is the amount of heat required to raise the temperature of a unit mass by one degree. It is a fundamental thermodynamic property.

Key Formulas

Heat Transfer

$Q = m c \Delta T$

Heat required to change temperature.

Specific Heat at Constant Pressure

$c_p = \left(\frac{\partial h}{\partial T}\right)_p$

Enthalpy change per degree at constant pressure.

Specific Heat at Constant Volume

$c_v = \left(\frac{\partial u}{\partial T}\right)_v$

Internal energy change per degree at constant volume.
