Liquid helium has a very low boiling point, 4.2 K, as well as a low latent heat of vaporization, equal to 2.09 x 104 J/kg. If energy is transferred to a container of liquid helium at the boiling point from an immersed electric heater at a rate of 10.0 W, how long does it take to boil away 2.00 kg of the liquid?
