1. One pound of an ideal gas undergoes an isentropic process from 95.3psig and a volume of 0.6ft3 to a final volume of 3.6 ft3. If cp = 0.124Btu/lb-R and cv = 0.093 Btu/lb-R, determine the final temperature of the gas (°F) and the work done by the
gas (Btu). Draw a figure, or graph that will support the problem. Explain each step by step formula.
A series of pistons / cylinders positioned horizontally within a constant- temperature bath. The piston can move in the cylinder without friction. There is a force outside which holds the piston in position, against the initial gas pressure equal to 14 bar. The volume of gas is initially 0.03 m3 . External force acting on the piston reduced gradually, and the gas is isothermal expansion until the volume is doubled. If the relationship between gas volume and pressure can be stated by: PVt = constant How much work did the gas do at the time of expansion? How much work is that will be carried by the gas if the external force is reduced suddenly to the force they will be half of the original force.
