Air contained in a rigid, insulated cubic tank of edge 1 m, fitted with a paddle wheel, undergoes a stirring process between state 1: t1 = 40 °c, p1 = 400 kpa; and state 2: p2 = 800 kpa.

(a). (4p) determine the temperature change in this process.
(b). (4p) determine the work done by the paddle wheel in this stirring process.
(c). (4p) determine the entropy generation in this process.
