Two frictionless pistons of area $A$ in a horizontal tube are joined by a wire. The gas between them is at $P_{0}$ and $T_{0}$ , with atmospheric pressure $P_{0}$ outside. The gas is heated to $3 T_{0}$ . The tension in the wire is:

Options:

Answer:

Solution:

The pistons are held by the wire, so the volume is fixed and

$P = 3 P_{0}$ . Net outward force on each piston =

$(3 P_{0} - P_{0}) A = 2 P_{0} A$ , which equals the tension. A.
