A gas is filled in the cylinder shown in fig. The two pistons are joined by a string. If the gas is heated, the right piston will

move toward left

move toward right

remain stationary

none of these

Text Solution

Verified by Experts

The correct Answer is:

b. When temperature of gas increase, it expands. An the cross-section area of right is more, greater force will work on it (because `F = PA`). So piston will move towards rigth.

An ideal monoatomic gas is confined in a horizontal cylinder by a spring loaded piston (as shown in the figure). Initially the gas is at temperature T_1 , pressure P_1 and volume V_1 and the spring is in its relaxed state. The gas is tehn heated very slowly to temperature T_2 ,pressure P_2 and volume V_2 . During this process the piston moves out by a distance x. Ignoring the friction between the piston and the cylinder, the correct statement (s) is (are)
