# NEET Physics Thermodynamics Questions Solved

An ideal gas is taken around ABCA as shown in the above P-V diagram. The work done during a cycle is

(1) Zero

(2) $\frac{1}{2}PV$

(3) 2 PV

(4) PV

(4) Work done = Area enclosed by the curve

$=\frac{1}{2}\left(3V-V\right)\text{\hspace{0.17em}}\left(2P-P\right)=PV$
