A horizontal cylinder 30 cm long is divided into equal halves by a frictionless insulating piston. Each half holds an equal mass of gas at 27°C. One half is heated to 87°C. Find the displacement of the piston in cm (two decimals).

Answer:

1.36

Solution:

At equilibrium the pressures are equal, so $(15 + x) / (15 - x) = (360) / (300) . x = 15 \times (60) / (660) = 1.36$ cm.
