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 when heated at constant volume
- B More when heated at constant pressure
- C Same in both the cases
- D Zero in both the cases
Answer & Solution
Correct Answer
(C) Same in both the cases
Step-by-step Solution
Detailed explanation
For mono atomic gas, \(\mathrm{f}=3\) At constant volume, \((\Delta \mathrm{U})_1=\frac{\mathrm{nfR} \Delta \mathrm{~T}}{2}=\frac{3 \mathrm{nR}\left(\mathrm{~T}_2-\mathrm{T}_1\right)}{2}\) At constant pressure,…
