What is the boiling point and melting point of air?

Question

I'm trying to figure out at what range of temperatures would air be a liquid. In order to do this I need to know its melting point and its boiling point. Anybody thing you know would be appreciated :)

Answer 1

Since air is a mixture, it's components melt or boil at different temps.

Answer 2

Boiling Point Of Air

Answer 3

The boiling point of a substance is where the liquid phase changes into gas phase. The melting point of a substance is where the solid phase changes into the liquid phase. Since air is a mixture of gases, it has no boiling point and it also has no melting point. I think what you meant to ask is at what temperature does air condense into a liquid and at what temperature does that liquid solidify. I don't know the answer, but I do know it is close to absolute zero. Also, before the temperature can be determined the pressure must be known, because the Ideal Gas Law states: PV=nRT, where P is pressure, V is volume, n is the amount of material, R is the Gas Constant, and T is Temperature. Gosh, Science has so many details that a simple answer just isn't possible.

Answer 4

Air is not a compound. It is a mixture of basically nitrogen and oxygen (with minor quantities of CO2, water and other gases). Since the mixture has different proportions of its constituent gases, it cannot be converted to liquid or solid at fixed temperatures. Moreover, by the same reason, it can not be converted to liquid or solid by reducing temperature alone - a mixture like air needs high pressure to condense/freeze. So the temperature in which a particular composition of air changes its state depends on the pressure.
Another thing, Boiling point and Melting point are the terms applied to the temperature (at 1 atm pressure) for a liquid to boil or a solid to melt, respectively. When the process is reversed, i.e., when you are converting a gas to its liquid or solid forms, the temperature is called condensation point or freezing point, respectively.

Answer 5

air is made up of different elements and compounds. It isn't fair to say what is the melting and boiling point. I can tell you for sure that the air will freeze by the time you reach 0 K or -273 C because this is the absolute zero. But that is just a theoretical value and has never been tested.

Answer 7

Melting point of pure water (difficult to find) is 0 degrees/ or 32 degrees Fahrenheit Boiling point of water= 100 degress centegrate/ or 212 degrees Fahrenheit
