The PT diagram for an ideal gas is shown in the figure, where AC is an adiabatic process, find the corresponding PV diagram.

Options

A.
B.
C.
D.

Answer

B

Explanation

(b) If we study the P-T graph we find AB to be a
isothermal process, AC is adiabatic process given. Also
for an expansion process, the slope of adiabatic curve
is more (or we can say that the area under the P-V
graph for isothermal process is more than adiabatic
process for same increase in volume). only graph (b) fits the above criteria.
