Liquid helium has a very low b$$ling point, $4\mathrm{.}2$ K $,$ as well as a very low latent heat of vaporization, $2\mathrm{.}00{10}^4\frac{J}{k}g.$ If energy is transferred to a container of liquid helium at the boiling point from an immersed electric heater at a rate of $30\mathrm{.}0$ W $,$ how long does it take to boil away $1\mathrm{.}70$ kg of the liquid?
