MHT CET 2024 Physics question
Two cylinders A and B fitted with piston contain equal amount of an ideal diatomic gas at temperature 'T' K. The piston of cylinder A is free to move while that of B is held fixed. The same amount of heat is given to the gas in each cylinder. If the rise in temperature of the gas in A is '' then the rise in temperature of the gas in cylinder B is
Answer: (C)
Solution
Let each cylinder contain moles and receive heat . In cylinder A the piston is free, so the gas expands at constant pressure: . In cylinder B the piston is fixed, so the volume is constant: . Equating,
