Find Cv, Cp and γ for (a) neon, a monatomic gas, and (b) nitrogen at room temperature, a diatomic…

Step 1. Neon. $C_v = \tfrac32 R = 12.5\ \text{J mol}^{-1}\text{K}^{-1}$, $C_p = \tfrac52 R = 20.8\ \text{J mol}^{-1}\text{K}^{-1}$, $\gamma = 1.67$.

Step 2. Nitrogen. $C_v = \tfrac52 R = 20.8\ \text{J mol}^{-1}\text{K}^{-1}$, $C_p = \tfrac72 R = 29.1\ \text{J mol}^{-1}\text{K}^{-1}$, $\gamma = 1.40$.

Step 3. Heat. Neon: $1.8\ \text{mol} \times 20.775\ \text{J mol}^{-1}\text{K}^{-1} \times 16\ \text{K} = 598\ \text{J}$. Nitrogen: $1.8\ \text{mol} \times 29.085\ \text{J mol}^{-1}\text{K}^{-1} \times 16\ \text{K} = 838\ \text{J}$.
