A movable piston having a mass of 7 kg and a, Ask an Expert

Academics

A movable piston having a mass of 7 kg and a cross-sectional area of 6 cm2 traps 0.25 mol of an ideal gas in a vertical cylinder. The piston slides without friction in the cylinder. The outside of the cylinder is kept at atmospheric pressure, 1.013×105 Pa.

What is the pressure in the cylinder?

How much work is done by the gas when its temperature is increased from 20°C to 305°C?

By what height was the piston raised?

What was the change in the gravitational potential energy of the piston?
