...with temperature at constant volume, (dP/dT)y = ß/xT, which we shall call a. In addition, there is the ratio of the specific heat at constant pressure to that at constant volume (C¡,¡CV), which has been written y . For any material, CyKT = CpKg, or KT = YKS; so we have a means...

...the specific heat of gases.7 If equipartition were admitted, then kinetic theory predicted that y, the ratio of the specific heat at constant pressure to that at constant volume, should be given by (n + 2)/n, with n the number of degrees of freedom of a gas molecule. To bring that...

...quantity 7 related to c\- through c, = ^— (6'4) / ' rather than c\-. One can easily show that y is the ratio of the specific heat at constant pressure to that at constant volume. For a monatomic gas, y has to be equal to 5/3 to give the correct factor 3/2 in the expression of internal...

...whether the equipartition theorem applies to the motions of atoms within a molecule. If it does, then the ratio of the specific heat at constant pressure to that at constant volume, 7 = Cpjcy, a parameter easily measurable from the speed of sound in the gas, should be equal at all...
