Question

Oxygen in a piston-‐‐cylinder assembly undergoes an expansion process in which the pressure varies with volume according to the following relation:
= !! +
where A = 0.05 bar-‐‐m3 and B = 3 bar. The initial volume is 0.01 m3 and the final volume is 0.025 m3. Determine the following:
a. Initial pressure in bar.b. Final pressure in bar.c. Boundary work in kJ.
