MHT CET 2025 Physics question
Two cylinders A and B fitted with pistons contain equal amount of an ideal rigid diatomic gas at 303 K. The piston of cylinder A is free to move and that of cylinder b is held fixed. The same amount heat is given to the gas in each cylinder. If the rise in temperature of the gas in cylinder B is 49 K, then the rise in temperature of the gas in A is
Answer: (B)
Solution
In cylinder B the piston is fixed, so the heating is at constant volume: . In cylinder A the piston is free, so the pressure stays constant: . Equal heat and equal amount of gas give , so T_AT_B$={Δ
