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 basketball is pressurized to a gauge pressure of PG = 75 kPa when at the surface of a swimming pool. (Patm = 101 kPa). The ball is then submerged in the pool of water which has a density ρ = 1000 kg/m3. Assume the ball does not change in mass, temperature, or volume as it is submerged. a) Calculate the absolute pressure inside the basketball in kPa when it is at the surface. b) Solve the pressure equation for the depth (in meters) at which the pressure difference between the inside and outside of the ball will become zero. At this depth the pressure inside the basketball is the same as the pressure outside the ball. c) At what depth, in meters, would the pressure difference between the inside and outside of the ball be zero if the ball were submerged in mercury (ρ = 13,500 kg/m3) instead of in water?
Incandescent lightbulbs are filled with an inert gas to lengthen the filament life. With the current off ( at T = 20.0 degrees Celsius ), the gas inside a lightbulb has a pressure of 113 kPa.

A cylinder containing ideal gas is sealed by a piston that is above the gas. The piston is a cylindrical object, with a weight of 22.0 N, which can slide up or down in the cylinder without friction. The inner radius of the cylinder, and the radius of the piston, is 8.00 cm. The top of the piston is exposed to the atmosphere, and the atmospheric pressure is 101.3 kPa. The cylinder has a height of 30.0 cm, and, when the temperature of the gas is 20°C, the bottom of the piston is 11.0 cm above the bottom of the cylinder.

Calculate the distance between the bottom of the cylinder and the bottom of the piston when the piston comes to its new equilibrium position.
