A gas is filled in the cylinder shown in the figure. The two pistons are joined by a string. If the gas is heated, the pistons will(a) Move towards left(b) Move towards right(c) Remain stationary(d) None of these

Answer»

Correct Option  (b) Move towards right

Explanation: 

When temperature of gas increases it expands. As the cross-sectional area of right piston is more, therefore greater force will work on it (because F = PA). So piston will move towards right.
