Ten dm^(3) of hydrogen under 1 bar pressure are conained in a cylinder which has a movable piston. The piston is moved in until the same mass of gas occupies 2 dm^(3) at the same temperature. Find the pressure in the cylinder.

Suppose a monatomic ideal gas is contained within a vertical cylinder that is fitted with a movable piston. The piston is frictionless and has a negligible mass. The area of the piston is 3.14 xx 10^(-2) m^2, and the pressure outside the cylinder is 1.01 xx 10^5 Pa. Heat (2093 J) is removed from the gas. Through what distance does the piston drop?
