Making SOLID Nitrogen!
What happens when you decrease the pressure around a liquid? It boils. Water boils at room temperature once the pressure is low enough. What is interesting is that this decreases the temperature...
==========
Boiling point is something that we normally think of as a stable property of a substance.But it really depends on what the pressure is around the substance,so, for example, water only boils at 100 degrees Celsius, if the pressure is 1 atmosphere.So if you reduce the pressure, then those water molecules that are going quite quicklycan easily escape from the water if there's no pressure pushing down on them.So you can get water to boil at room temperature.This is really boiling water.The funny thing about boiling water at room temperatureis that it actually decreases the temperature of the water.That's because all the fastest water molecules escape,leaving only the slow ones behind.We are refrigerating the waterRefrigerating the water, by boiling it.Y...
