MCQ
Consider the processes A and B shown in the figure. It is possible that:
- ABoth the processes are isothermal.
- BBoth the processes are adiabatic.
- ✓A is isothermal and B is adiabatic.
- DA is adiabatic and B is isothermal.
✓
Answer
Correct option: C.
A is isothermal and B is adiabatic.
The slope of an adiabatic process is greater than that of an isothermal process. Since A and B are initiated from the same initial state, both cannot be isothermal or adiabatic, as they would be overlapping. But the curve of process B is steeper than the curve of process A. Hence, A is isothermal and B is adiabatic.
