Aclosed system consisting of 2 kg of a gas undergoes a process during which the relation between pressure and volume is pl" = constant. the process begins with pi = 100 kpa, v, = 0.078 m/kg, and ends with p2 = 350 kpa, v2 = 0.0125 m /kg. (a.) determine the volume in m and in liters, occupied by the gas at the initial state 1 (v) and at the final state 2 (v2). (b) determine the value of n. (c) make a sketch of the process 1-2 on a graph with coordinates p vs. v.
