22 //! Defined as the quantity of heat required to raise
23 //! unit mass by one degree temperature. For a gas
24 //! there are two values: one at constant pressure, the
25 //! other at constant volume. Their ratio is linked to the
26 //! speed of sound in the gas and to the number of
27 //! degrees of freedom of the molecules.
28 //! It is quantified as energy per unit mass per
29 //! degree of temperature.
30 //! It is measured in joules per kilogram per degree
