Two cylinders A and B fitted with pistons contain equal amounts of an ideal diatomic gas at 300K.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 :
