A long cylindrical pipe of radius 20 cm ...

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 pistion, it moves down by a distance`Deltal` before coming to equilibrium. Assuming air to be an ideal gas, `Deltal//L` (see figure) is close to (g = 10 `ms^(2)` , atmospheric pressure is `10^(5)` Pascal),

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 pistion, it moves down. If the air in the enclosure is cooled from temperature T to T – DeltaT , the piston moves back to its original position. Then DeltaT//T is close to (Assuming air to be an ideal gas, g = 10 m//s^(2) , atmospheric pressure is 10_(5) Pascal),
