Two m^3 of air in a rigid, insulated container fitted with a paddle wheelis initially at 293 k, 200 kpa. the air receives 710 kj by work from the paddle wheel. assuming the ideal gas model with cv=0.72 kj/kg. k, determine for the air (a) the mass, in kg, (b) final temperature, in k, and (c) the amount of entropy produced, in kj/k.
