1. The problem statement, all variables and given/known data The problem is derive the adiabatic processes for an ideal gas going through a point (v,p) on the p-V plane. Also, in terms of p,T and v,T. Draw the curves. 2. Relevant equations First Law of Thermo Properties of an Ideal Gas Properties of Adiabatic Processes 3. The attempt at a solution I derived the transformations, but I am getting the impression from the wording that I have to draw all three curves on the p-V diagram. Yet, I don't know. I figure I have to plot the other two in their respective planes.
