SOLID NITROGEN

SOLID NITROGEN. To make a solid nitrogen, liquid nitrogen is poured into the container and place the vacuum unit. Begin to pump air pressure drops, the liquid nitrogen starts to cool and the solid state switch. We get solid nitrogen. If you open the cover of the vacuum unit, the pressure increases, solid nitrogen is quickly transferred to a liquid state. Again, make solid nitrogen. We include the evaporator. The solid nitrogen will evaporate without going through the liquid state. Nitrogen - element of the
