Question

state the law of equipartition of energy and prove that for a diatomic gas the ratio of the two specific heat at room temperature is 7/5​

Answer 1

Answer:

For a system in thermal equilibrium ,the law of equipartition of energy states that the total energy  for the system is equally divided among the degree  of freedom.

Explanation:

1/2M(Vrms)²=3/2KT.

For a diatomic gas,

Cp=Cv +R

Molar heat capacity at constant pressure,Cp=7/2 R

Molar heat capacity at constant volume,Cv=5/2 R

∴Cp/Cv=$\frac{7/2 R}{5/2 R}$ =7/5
