Question

A gas is confined in the cylinder under a light piston which is connected to the bottom of the
cylinder with a weightless spring as shown in figure, under pressure p = 0.1 MPa and
temperature To 27°C. The initial pressure of the gas is equal to the external atmospheric
pressure. If the gas under the piston is fully pumped out, the piston will reach the bottom of the
vessel compressing the spring completely just touching the bottom. Now we heat the gas to
increase its volume to n = 1.2 times then the final temperature of gas is
A 528 K
B 432 K
C 745 K
D 620 K​
