Two cylinder A and B fitted with pistons contain equal amount of an ideal diatomic gas a 300 K. The piston of 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 30 K, then the rise in temperature of the gas in B is –
A
30 K
B
18 K
C
50 K
D
42 K
Answer
50 K
Explanation
Solution
Adiabatic ® B PVg = constant
Isothermal ® A PV = constant
\ PB > PA OR PA > PB
