Question

Consider the processes A and B shown in the figure. It is possible that
Figure
(a) both the processes are isothermal
(b) both the processes are adiabatic
(c) A is isothermal and B is adiabatic
(d) A is adiabatic and B is isothermal

Answer 1

The correct answer is (c), which is A is isothermal and B is adiabatic.

Explanation:

• The slope of an isothermal process is lesser than the adiabatic process.

• From the same initial state, since B and A are initiated from the same initial state, both can be adiabatic or isothermal as there will be some overlapping.

• But the process B curve is steeper than the process A curve. Therefore, B is adiabatic, and A is isothermal.

Answer 2

Answer:

(c) - A is isothermal and B is adiabatic
