Q1. A 40 cm diameter vertical cylinder is sealed at the top by a frictionless 22 kg piston. The piston is 79 cm above the bottom while the gas temperature is 315 C. The air above the piston is at 1.20 pressures.
What is the gas pressure inside the cylinder?
Why heights will the piston be if the temperature is lowered to 10 C?
