Question 58: Thermodynamics & KTG

Question

The mean energy per molecule for a diatomic gas is

Accepted Answer

For an ideal gas, mean kinetic energy per molecule
$$=\frac{f}{2} k_B T$$
For diatomic gas, degree of freedom,
$$\begin{gathered}
f=5 \
	herefore 	ext { K.E per molecule }=\frac{5 k_B T}{2}
\end{gathered}$$

Answer

$$\frac{5 k_B T}{N}$$

Answer

$$\frac{5 k_B T}{2 N}$$

Answer

$$\frac{5 k_B T}{2}$$

Answer

$$\frac{3 k_B T}{2}$$
