Problem 8.05**. A high-pressure gas cylinder contains 50.0 L of toxic gas at a pressure of 1.40 × 107 N/m² and a temperature of 25.0°C. Its valve leaks after the cylinder is dropped. The cylinder is cooled to dry ice temperature (-78.5ºC) to reduce the leak rate and pressure so that it can be safely repaired. (a) What is the final pressure in the tank, assuming a negligible amount of gas leaks while being cooled and that there is no phase change? [9.14 × 106 Pa] (b) What is the final pressure if one-tenth of the gas escapes? [8.23 × 106 Pa] (c) To what temperature must the tank be cooled to reduce the pressure to 1.00 atm (assuming the gas does not change phase and that there is no leakage during cooling)? [2.16 K]

A closed system consisting of 2 lb of a gas undergoes a process during which the relation between pressure and volume is pV" = constant. The process begins with p₁ = 25 lbf/in², V₁ = 13 ft³ and ends with p2 = 100 lbf/in². The value of n = 1.3. Determine the final volume, V₂, in ft3, and determine the specific volume at states 1 and 2, in ft³/lb.
15.01 A cylindrical tank has a tight-fitting piston that allows the volume of the tank to be changed. The tank originally contains 0.100 m3m3 of air at a pressure of 3.10 atm. The piston is slowly pulled out until the volume of the gas is increased to 0.390 m3 . If the temperature remains constant, what is the final value of the pressure? Express your answer in atmospheres.
A vertical cylindrical tank contains 1.80 mol of an ideal gas tinder a pressure of 0.300 atm at 20.0°C.
