The molar heat capacity at constant volume of oxygen gas at STP is nearly 2.5 R. As the temperature is increased, it gradually increases and approaches 3.5 R. The most appropriate reason for this behaviour is that at high temperatures
Text Solution
Verified by ExpertsThe correct answer is:
D
C V = 2.5 R
As temperature increases, vibrational degree of freedom becomes 2 at high temperature.
C V = 
R = 3.5 R
