Problem

Two cylinders

A

and

B

fitted with pistons contain equal amounts of an ideal diatomic gas at 300 K. The piston of

A

is free to move, while that

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

30 \text{ K}

, then the rise in temperature of the gas in

B

is a.

30 \text{ K}

18 \text{ K}

50 \text{ K}

42 \text{ K}
