MCQ
Which is the correct statement
- ✓For an isothermal change $PV =$ constant
- BIn an isothermal process the change in internal energy must be equal to the work done
- CFor an adiabatic change $\frac{{{P_2}}}{{{P_1}}} = {\left( {\frac{{{V_2}}}{{{V_1}}}} \right)^\gamma }$, where $\gamma $ is the ratio of specific heats
- DIn an adiabatic process work done must be equal to the heat entering the system
