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 flask with a volume of 1.70 L , provided with a stopcock, contains ethane gas (C2H6) at a temperature of 297 K and atmospheric pressure 1.013×105 Pa . The molar mass of ethane is 30.1 g/mol . The system is warmed to a temperature of 379 K , with the stopcock open to the atmosphere. The stopcock is then closed, and the flask cooled to its original temperature. What is the final pressure of the ethane in the flask?...

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...
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?...
