"Spaceman Spiff sits just outside the Milky Way galaxy with a cup of liquid Helium which is at approximately 4K (-269 0C).He has with him a small sphere made entirely of copper which is at a temperature of 219K (-54 0C).After a certain amount of time his copper sphere comes into equilibrium with the liquid Helium. If his sphere has a diameter of 1.6 cm,a mass density of 8.96 g/cm3,and a specific heat of 0.386 J/(gK),and if Helium has a latent heat of vaporisation of 21 J/g,How much Helium would be boiled off?"
