First law of thermodynamicsthe state of 30 moles of steam in a cylinder is changed in a cyclic manner from a-b-c-a, where the pressure and volume ofthe states are: a (30 atm, 20 l), b [50 atm. 20 l). and c (50 atm, 45 l). assume each change takes place along the lineconnecting the initial and final states in the pv plane. (a) display the cycle in the w plane. (b) find the net work done bythe steam in one cycle. (c) find the net amount of heat flow in the steam over the course of one cycle.
