Question

Two pistons of areas 10 cm² (left) and 30 cm² (right) are joined by a rod and move in a horizontal cylinder of two sections. Gas is trapped between them and air at pressure P 0 ​ acts on the outer faces. The gas is heated. The pistons will:

TestHub · Accepted Answer

Net force to the right = P ( A 2 ​ − A 1 ​ ) − P 0 ​ ( A 2 ​ − A 1 ​ ) = ( P − P 0 ​ ) ( A 2 ​ − A 1 ​ ) . Heating raises P above P 0 ​ , so the pistons move towards the larger section (right). B.
