    A long cylindrical pipe of radius $20 \,cm$ is closed at its upper end and has an airtight piston of negligible mass as shown. When a $50 \,kg$ mass is attached to the other end of the piston, it moves down. If the air in the enclosure is cooled from temperature $T$ to $T-\Delta T$, the piston moves back to its original position. Then $\Delta T / T$ is close to (Assuming air to be an ideal gas, $g=10 \,m / s ^2$, atmospheric pressure is $10^5 \,Pa$ )
