Triple point of nitrogen

Référence de la vidéo 11945401
Triple point of nitrogen. Close-up footage of liquid nitrogen in a gas jar being brought to its triple point as the pressure is reduced using a pump. The triple point is where a substance exists in three phases (gas, liquid and solid) in thermodynamic equilibrium. For nitrogen, this point is at 0.124 of an atmosphere and a temperature of minus 210 degrees Celsius. Nitrogen ice and gas both form along with the liquid when the triple point is reached. At the end of the clip, the pressure is restored to normal. For a wider view of this experiment, see clip K005/4122.
