Spaceman Spiff sits just outside the Milky Way galaxy with a cup of liquidHelium which is at approximately 4K (-269 °C). He has with him a small spheremade entirely of copper which is at a temperature of 219K (-54 °C). After a certain amountof time his copper sphere comes into equilibrium with the liquid Helium. If his sphere has adiameter of 2 cm, a mass density of 8.96 g/cm3, and a specific heat of 0.386 J * K-1 * g-1, andthe process of the copper coming into equilibrium with the liquid helium burned off 150g ofliquid Helium, what is the latent heat of vaporization of liquid Helium? (Assume that 4K isthe boiling point of He and there is more than 150g of He)Click here to enter text.
