A vertical cylinder of cross-sectional area A is fitted with a tight-fitting, frictionless piston of mass m (Fig. P18.40). The piston is not restricted in its motion in any way and is supported by the gas at pressure P below it. Atmospheric pressure is P 0 . We wish to find the height h in Figure P18.40. (a) What analysis model is appropriate to describe the piston? (b) Write an appropriate force equation for the piston from this analysis model in terms of P , P 0 , m , A , and g . (c) Suppose n moles of an ideal gas are in the cylinder at a temperature of T . Substitute for P in your answer to part (b) to find the height h of the piston above the bottom of the cylinder.
