62 consider 2.0 kg of a 99.6 wt% fe–0.4 wt% c alloy that is cooled to a temperature just below the eutectoid. (a) how many kilograms of proeutectoid ferrite form? (b) how many kilograms of eutectoid ferrite form? (c) how many kilograms of cementite form?

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg • k, determine for the air the amount of entropy produced, in kj/k
