Q.
A monoatomic gas of $n$-moles is heated from temperature $T_{1}$ to $T_{2}$ under two different conditions (i) at constant volume and (ii) at constant pressure. The change in internal energy of the gas is
A) More for (i)
B) More for (ii)
C) Same in both cases
D) Independent of number of moles
Explanation
(c) Change in internal energy $\mathrm{\Delta}U = \mu C_{V}\mathrm{\Delta}T$
It doesn’t depend upon type of process. Actually it is a state function
