Q.
For a diatomic gas change in internal energy for unit change in temperature for constant volume is $U_{1}$ and $U_{2}$ respectively. $U_{1}: U_{2}$ is
Kinetic Theory
Solution:
The temperature rises by the same amount in the two cases and the internal energy of an ideal gas depends only on it's temperature
Hence $\frac{U_{1}}{U_{2}}=\frac{1}{1}$
