The latent heat of vaporization of liquid nitrogen is about 200kJ/kg. Suppose you have 6 kg of liquid nitrogen boiling at 77 K. Ifyou supply heat at a constant rate of 45 W via an electric heaterimmersed in the liquid nitrogen, how long will it take to vaporizeall of it?
What is the time for 6 kg of liquid helium, whose heat ofvaporization is 20.9 kJ/kg?
