A high-pressure gas cylinder contains 70.0 L of toxic gas at a pressure of 1.50x10^7 N/m2 and a temperature of 24.0°C. Its valve leaks after the cylinder is dropped. The cylinder is cooled to dry ice temperatures (−78.5°C), 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? N/m2 (b)...

For many purposes we can treat propane (CH) as an ideal gas at temperatures above its boiling point of -42. C. Suppose the temperature of a sample of propane gas is lowered from 14.0 °C to -16.0 °C, and at the same time the pressure is changed. If the initial pressure was 1.3 atm and the volume decreased by 45.0%, what is the final pressure? Round your answer to 2 significant digits. 1 atm

For many purposes we can treat ammonia (NH) as an ideal gas at temperatures above its boiling point of -33.C. Suppose the temperature of a sample of ammonia gas is raised from -21.0°C to 23.0°C, and at the same time the pressure is changed. If the initial pressure was 4.6 atm and the volume decreased by 50.0%, what is the final pressure? Round your answer to 2 significant digits. atm OP x 5 ?
Electrical generating plants operate by generating steam at elevated temperatures and pressures then reducing the pressure...
Electrical generating plants operate by generating steam at elevated temperatures and pressures then reducing the pressure in a turbine. As the pressure is reduced, high temperature steam expands (and cools) driving the turbine. The shaft work produced by the turbine is transferred to a generator to generate electricity. One limitation on steam turbines is that they cannot tolerate small amounts of water in its liquid state in the gases passing through the turbine. If the liquid content of the steam...
