The cosmic microwave background radiation exists slightly above this condition, as do both lambda points for helium. Bose-Einstein condensates also exist at points near this condition. The Third Law of Thermodynamics states that the entropy of a perfect crystal is (*) zero at this condition. A simple way to determine the value for this condition is to graph the relationship between a gas's temperature and its pressure, then extrapolate the line to where pressure equals zero. For 10 points, name this temperature roughly equal to negative 273 degrees Celsius.
