Heat And Thermodynamics

Specific heats of an ideal gas at constant pressure and volume are denoted by \(\mathrm{C}_{\mathrm{p}}\) and \(\mathrm{C}_{\mathrm{v}}\) respectively. If \(\gamma=\frac{\mathrm{C}_{\mathrm{p}}}{\mathrm{C}_{\mathrm{v}}}\) and \(\mathrm{R}\) it's the universal gas constant then \(\mathrm{C}_{\mathrm{v}}\) is equal to
