Two cylinders A and B fitted with pistons contain equal amount of an ideal diatomic gas at 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
