    Joshuelle,

    In its liquid state, the answer is -- of heat, yes: "Liquid helium below its lambda point begins to exhibit very unusual characteristics, in a state called helium II. Boiling of helium II is not possible due to its high thermal conductivity; heat input instead causes evaporation of the liquid directly to gas. "

    "The thermal conductivity of helium II is greater than that of any other known substance, a million times that of helium I and several hundred times that of copper."

    Of electricity, no: "It is an electrical insulator unless ionized."

    Hope that helped!

    Helium is a gas. In general, gases are poor conductors of electricity and heat.
