He gas is confined to a piston and cylinder with a mechanical stop that prevents the cylinder from expanding. The temperature of the gas is 298 K, the volume of gas in the cylinder is 1.20 L and its pressure is 2.15 bar. The ideal gas EOS is very accurate for He under these conditions. The mechanical stop is a nut on a threaded rod that can be turned, slowly allowing the gas in the cylinder to expand. This process...

He gas is confined to a piston and cylinder with a mechanical stop that prevents the cylinder from expanding. The temperature of the gas is 298 K, the volume of gas in the cylinder is 1.20 L and its pressure is 2.15 bar. The ideal gas EOS is very accurate for He under these conditions. Starting from the final state of the He gas in part (b), the gas (and apparatus) was cooled from 298 K to 263 K. The...
What is the gas pressure inside the cylinder?
A 20 cm--diameter vertical cylinder is sealed at the top by a frictionless 22 kg piston. The piston is 79 cm above the bottom when the gas temperature is 304 C.The air above the piston is at 1.00 atm pressure.a) What is the gas pressure inside the cylinder?b) What will the pressure be if the temperature is lowered to 20 C?c) What will the height of the piston be if the temperature is lowered to 20 C?

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...

* A gas is contained in a vertical, frictionless piston-cylinder device. The piston has a mass of 2 kg and a cross-sectional area of 30 cm2. A spring above the piston is compressed by 2.5 mm and has a spring constant, k, of 38 kN/m. a. If the atmospheric pressure is 1 atm, determine the initial pressure (P1) inside the cylinder. Heat is added to the system until the piston moves an additional 10 mm. b. How much did the...

P3A.2 A sample consisting of 0.10 mol of perfect gas muICLUL is piston inside a cylinder such that the volume is 1.25 dm'; the external pressure is constant at 1.00 bar and the temperature is maintained at 300 K by a thermostat. The piston is released so that the gas can expand. Calculate (a) the volume of the gas when the expansion is complete; (b) the work done when the gas expands; (c) the heat absorbed by the system. Hence...
