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
A) $5\ :3$
B) $3\ :5$
C) $1\ :1$
D) $5\ :7$
Explanation
(c) 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 $\frac{U_{1}}{U_{2}} = \frac{1}{1}$
