For 10 points, name this value equal to minus 273.15 degrees Celsius, the coldest possible temperature.
Bose-Einstein condensates only exist close to this condition. The third law of thermodynamics states that in this condition, a perfect crystal has no (*) entropy. Superfluidity and superconductivity exist mainly near this condition, at which particles have minimal vibrational motion. For 10 points, name this value equal to minus 273.15 degrees Celsius, the coldest possible temperature.
