A heat-insulated evacuated vessel with a volume of 15 liters is filled with 2 kg of water at 300° K. At the bottom of the vessel, a wire with a resistance of 100 cm is soldered into the vessel, through which a current of 2 A flows. Determine the time during which the temperature in the vessel reaches 100° C. Neglect the change in the volume of water.
