Smoking near a leaking gas cylinder is dangerous because

The gas we use in the kitchen is called liquified petroleum gas (LPG). In the cylinder it exists as a liquid. When it comes out from the cylinder it becomes a gas (change-A) then it burns (change-B). The following statements pertain to these changes. Choose the correct one.

Two cylinder A and B having piston conneted by massless rod (as shown in figure). The cross-sectional area two cylinders are same & equal to 'S'.The cylinder A contains m gm of an ideal gas at Pressure P & temperature T_(0) The cylinder B contain identical gas at same temperature T_(0) but has different mass. The piston is held at the state in the position so that volume of gas in cylinder A & cylinder B are same and is equal to V_(0) . The walls & piston of cylinder A are thermally insulated, whereas cylinder B is maintained at temperature T_(0) reservoir. The whole system is in vacuum. Now the piston is slowly released and it moves towards left & machanical equilibrium is reached at the state when the volume of gas in cylinder A becomes V_(0)/2 Then (here gamma for gas =1.5) If work done by gas in cylinder B is W_(B) & work done by gas in cylinder A is W_(A) then

Two cylinders of equal size are filled with equal amount of ideal diatomic gas at room temperature. Both the cylinders are fitted with pistons. In cylinder A the piston is free to move, while in cylinder B the piston is fixed. When same amount of heat is added to both the cylinders, the temperature of the gas in cylinder A raises by 20 K. What will be the rise in temperature of the gas in cylinder B?
