Carbon dioxide (co2) is compressed in a piston-cylinder assembly from p1 = 0.7 bar, t1 = 320 k to p2 = 11 bar. the initial volume is 0.262 m3 . the process is described by pv1.25 = constant.
assuming ideal gas behavior and neglecting kinetic and potential energy effects, determine the work and heat transfer for the process, each in kj, for (a) constant specific heats evaluated at 300k, and (b) data from table a- 23.
compare the results and discuss.
