A sealed vessel with a capacity V = 0.25 m3 contains nitrogen under pressure p1 = 120 kPa. What pressure will be established in the vessel if the amount of heat Q = 8.4 kJ is given to nitrogen? The molar heat capacity of nitrogen under these conditions is C = 21 J/(mol • K). The universal gas constant is R = 8.31 J/(mol • K).
