Note: Show all your steps (sketches, formula, substitution, calculation) to get full credit. Problem 1: A gas in a piston-cylinder assembly undergoes an expansion process for which the relationship between pressure and volume is given by pV"=constant. The initial pressure is 3 bar, the initial volume is 0.1 m³, and the final volume is 0.2 m². Determine the work for the process, in kJ, if (a) n = 1.5, (b) n 1.0, and (c) n = 0.
