A cylinder contains 9.8 moles of ideal gas, initially at a temperature of 119°C. The cylinder is provided with a frictionless piston, which maintains a constant pressure of 7.4 × 105 Pa on the gas. The gas is cooled until its temperature has decreased to 27°C. For the gas CV = 14.41 J/mol ∙ K, and the ideal gas constant R = 8.314 J/mol · K. (a) Find the work done by (or on) the gas during this process. Is...

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...
