Triple point of nitrogen

Référence de la vidéo 11945400
Triple point of nitrogen. 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. The pressure gauge shows the reduction in pressure towards this point. 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 close-up of this experiment, see clip K005/4123.
