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)...
A high-pressure gas cylinder contains 50.0 L of toxic gas at a pressure of 1.40×107N/m2 and a temperature of 25.0°C. The cylinder is cooled to dry ice temperature (−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? (b) What is the final pressure if one-tenth of the gas...
A 7.86-L cylinder contains 1.70 mol of gas A and 3.63 mol of gas B, at a temperature of 33.8 °C. Calculate the partial pressure of each gas in the cylinder. Assume ideal gas behavior. PA= PB= What is the total pressure? Ptotal= Answers in kPa.
9. (8 points) A 1.72 L cylinder with a moveable piston contains nitrogen gas at a pressure of 0.985 atm and a temperature of 44°C. The gas is cooled while the pressure is maintained constant until the cylinder volume reaches 1.18 L. What is the final temperature (in °C) of the gas? 300
A gas in a cylinder sealed with a piston having negligible friction has a pressure of 5 atm and a volume of 6 liters. The piston is pushed in order to compress the gas to 1/7 of its original volume. Assume that there is no change in the temperature of the gas. A valve is opened to let enough gas escape until the pressure is reduced back to its original original value of 5 atm. it is 14.3 % Then...
105Pa, initial temperature T-300K, and an initial 1. An ideal gas with initial pressure 2 volume V - 1m3 expands isothermally to a final volume of 2m3. Then, the gas returns to its initial state, first by constant pressure (isobaric) contraction, and then by a change at constant volume (isochoric) a) Draw a PV diagram of this process. What's the total change in thermal energy of the entire process? b) What's the work done by the environment on the gas?...
chemistry ercise 5.121 A natural gas storage tank is a cylinder with a moveable top whose volume can change only as its height changes. Its radius remains fixed. The height of the cylinder is 225 mon a day when the temperature is 22" The next day the height of the cylinder increases to 232 m as the gas expands because of a heat wave Part A Find the temperature suming that the pressure and amount of gas in the storage...
