Harry, MENTOR Vuxen, Australia 0 poäng (VäTE)		February 12, 2009 09:03 A further update to my suggestions above. If we restrict ourselves to matter that behaves as an "ideal gas" then at a temperature of absolute zero, the volume of an ideal gas would indeed be zero. The ideal gas model is a model of matter in which the molecules are treated as non-interacting point particles which are engaged in a random motion that obeys conservation of energy. However, real matter doesn't behave exactly as an "ideal gas" particularly as temperatures fall to absolute zero. Real gases tend to become liquids long before absolute zero is reached. So they still have volume as absolute zero is approached.
