Consider a piston–cylinder assembly containing 0.1 kg of dry air initially at 300 K and 200 kPa (state 1). Energy is added to the air (by heat transfer) at constant pressure until the final temperature is 450 K at state 2. Plot the process in P–v and T–v coordinates and determine the following quantities: ₁W₂, ΔU, ΔH, and ₁Q₂. Give units.
