Sealed inside a rigid, poorly insulated vessel is 3 m^3 of diatomic nitrogen. The system is at 1 bar, and the saturated nitrogen is 30% vapor by mass. The vessel will rupture if the pressure reaches 10 bar. Heat transfer from the surrounding atmosphere enters at an average rate of 70 kJ per hour. Determine the time interval before the vessel ruptures, in hours.
