An ideal gas contained in a pistoncylinder device expands isothermally at 120 F from state 1 to

Question:

An ideal gas contained in a piston–cylinder device expands isothermally at 120 F from state 1 to state 2.

A. If the expansion process is reversible and 20 Btu of heat is transferred from the surroundings to the gas, determine the increase in entropy (Btu/R) of the gas.

B. What is the P–v work done in this process?

C. If there is 1.3 lb_m of air in the piston-cylinder device initially at 15 psia, find the initial and final volumes of the air.
