A cylinder with an interior cross-sectional area of 70.0 cm2 has a moveable piston of mass 5.40 kg at the top that can move up and down without friction. The cylinder contains 2.25 × 10−3 mol of an ideal gas at 23.0 °C.
(a) What is the volume of the gas when the piston is in equilibrium? Assume the air pressure outside the cylinder is 1.00 atm.
(b) By what factor does the volume change if the gas temperature is raised to 223.0 °C and the piston moves until it is again in equilibrium?
