Helium was first discovered in space before it was on earth
A liquid boils at a temperature at which its vapor pressure is equal to the pressure of the gas above it. The lower the pressure of a gas above a liquid, the lower the temperature at which the liquid will boil. Boiling point represents a phase change of matter. So no, the boiling poibt of a liquid does not depend on the amount of liquid
