The PV graph is for an ideal gas cycle. Take AB as vertical & BC as horizontal. Let VA = 0.06 m3, Vc= 0.02 m3, Pc = 6 x 105 Pa, & TB = 900K. Take process C to A as isothermal.\f2.a. Find the work done BY the gas in B to C? Show reasoning, including for the sign. b. Find the work done BY the gas in isothermal process C to A? Show work in symbols first then values plugged in, then answer with units. Use your equation sheet to help. c. What is the work done BY the gas in process A to B? Give reasoning. d. The purpose of an engine is to do work. Is cycle A to B to C to A, an engine? Explain why it is or isn't
