In the cylinder shown below the two pistons are connected by a string. Assume that the piston can move freely, what happens when the gas trapped between the pistons are heated?


$\begin{array}{1 1} \text{both pistons will move to the left} \\ \text{both pistons will move to the right} \\ \text{both pistons will move away from each other} \\ \text{both pistons will remain stationery} \end{array}$

Can you answer this question?

Since heating the gas will increase the presure, the movement of the piston will be such that the movement will increase the volume of the gas and hence reduce the pressure. So, the pistons will move to the right.
