1. One cubic meter of argon is taken from 1 bar and 25 °C to 10 bar and 300 °C by each of the following two- step paths. For each path, compute Q, W, AU and AH for each step and for the overall process. Assume reversibility and treat argon as an ideal gas with cp = (5/2)R and c, = (a) Isothermal compression followed by isobaric heating. (b) Adiabatic compression followed by isobaric heating or cooling. (c) Adiabatic compression followed by isochoric heating or cooling. (3/2)R.
