Question
Consider the processes A and B shown in the figure. It is possible that
Options
both the processes are isothermal
both the processes are adiabatic
A is isothermal and B is adiabatic
A is adiabatic and B is isothermal

Solution
A is isothermal and B is adiabatic
The slope of an adiabatic process is greater than that of an isothermal process. Since Aand 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.
