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. 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),

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),
