No. Liquid oxygen and gaseous oxygen are the same substance, just in different states.
No. Hydrogen and oxygen will only react at high temperatures.
Actually, what you breathe in is a mixture of nitrogen (~79%) and oxygen (~21%). It means that both of them (therefore oxygen, too) are in gaseous stat (not liquid).
No, a gas is a state of matter. oxygen can be found in either liquid or gaseous states
Ability to react with oxygen in the air is a chemical property.
Yes, all of them.
think of H2Q water ? hydrogen and oxygen
No, liquid oxygen and liquid hydrogen would be rather explosive and in fact has been used for rocket fuel. Alternate answer: No, while water is comprised of Hydrogen and Oxygen, the two usually combine when in a gaseous form.
The gaseous element is oxygen.
Oxygen, on earth, is a gas because it is in a gaseous state. On mars, it is liquid. The physical state of any element like hydrogen, nitrogen, oxygen, sodium, sulfur, etc depends on the ambient temperature and pressure. The earth's atmosphere doesn't pressurize oxygen enough for it to turn into a liquid, nor is cold enough for oxygen to condense into a liquid. Hence oxygen is a gas.
Matter can be broadly categorized into solid, liquid or gaseous state, what is it that makes the matter remain in one of these state, this animated science topic gives in-depth information about states of matter.
Cool the gases to a temperture between the boiling points of the two gases. Nitrgen condenses to a liquid at a higher temperaturte than oxygen. So liquid nitrogen is drawn off and gaseous oxygen remains.
The change in state would be known as melting. Just for your information: Solid to Liquid = Melting Liquid to Gaseous = Boiling Solid to Gaseous = Sublimation Gaseous to Liquid = Condensation Liquid to Solid = Freezing Gaseous to Solid = Deposition
