A closed system consisting of 3 lb of a gas undergoes a process during which the relation between pressure and volume is pV = constant. The process begins with p,

= 15 lbf/in., v = 1.25 ft/lb and ends with p2 = 46 lbf/in.,V =0.5 ft/lb. Determine (a) the volume, in ft, occupied by the gas at states 1 and 2 and (b) the value of n. Determine the value of n. Determine the volume, in ft, occupied by the gas at states 1 and 2.
