MHT CET 2021 21th September Evening Shift | Heat and Thermodynamics Question 299 | Physics

If '$$\mathrm{E}$$' is the kinetic energy per mole of an ideal gas and '$$\mathrm{T}$$' is the absolute temperature, then the universal gas constant is given as

$$\frac{2 \mathrm{~T}}{3 \mathrm{E}}$$

$$\frac{2 \mathrm{E}}{3 \mathrm{~T}}$$

$$\frac{3 \mathrm{~T}}{2 \mathrm{E}}$$

$$\frac{3 \mathrm{E}}{2 \mathrm{~T}}$$

The molar specific heats of an ideal gas at constant pressure and volume are denoted by '$$\mathrm{C}_{\mathrm{p}}$$' and '$$C_v$$' respectively. If $$\gamma=\frac{C_p}{C_v}$$ and '$$R$$' is universal gas constant, then $$C_v$$ is equal to

$$\frac{\mathrm{R}}{\gamma-1}$$

$$\gamma \mathrm{R}$$

$$\frac{1+\gamma}{1-\gamma}$$

$$\frac{\gamma-1}{\mathrm{R}}$$
