For 10 points, name this measure of the heat needed to raise the temperature of a substance by one degree Celsius.
The NTU method finds the product of the mass flow rate and this quantity. The product of volume, temperature, and coefficient of thermal expansion squared, divided by the isothermal compressibility, equals the difference between two forms of this property according to Mayer's relation. This property is equal to approximately 3R per mole of a crystalline substance according to the (*) Dulong-Petit Law. The adiabatic index is the ratio between the values for this property at constant pressure and constant volume. The extensive form of this property has the same units as entropy, and can be found by dividing heat by temperature change. For 10 points, name this measure of the heat needed to raise the temperature of a substance by one degree Celsius.
