Question: Carbon dioxide (CO2) gas within a piston-cylinder assembly undergoes an expansion from a state where P1= 20 lbf/in2, V1= 0.5ft3 to a state where P2=5

Carbon dioxide (CO2) gas within a piston-cylinder assembly undergoes an expansion from a state where P1= 20 lbf/in2, V1= 0.5ft3 to a state where P2=5 lbf/in2, V2= 2.5ft3. the relationship between pressure and volume during the process is ρ= A+BV, where A and B are constant.
(a) For the CO2 evaluate the work, in ft. lbf and Btu.
(b) Evaluate A, in lbf/in.2, and B, in (lbf/in2)/ft3.
