Oxygen is a gas (in both forms: O2 and O3) at normal pressure and temperature.
its a gas
gas
gas liquid and solid
Ice is a solid. water is a liquid. and oxygen is a gas
Since oxygen is usually a gas, what is found in the tank (at room temperature) is a gas.
The answer is trivial. Some are solid, some liquid and some are gas. The solid ones are those (that at normal conditions) are not liquid (such as mercury) nor a gas (such as oxygen).
solid: iron + copper? liquid: mercury gas: hydrogen,oxygen, nitrogen
Solid
Yes it is. It changes from the state of Gas to liquid oxygen. changing from gas to liquid to solid are all physical changes(states of matter).
General classes of colloids are: gas in liquid, gas in solid, liquid in gas, liquid in liquid, liquid in solid, solid in gas, solid in liquid, solid in solid.
Oxygen is a gas at room temperature. It becomes a liquid at -183oC and a solid at -218.8oC.
H2O has solid liquid and gas phases oxygen itself is only a gas it does not have phases it must be combined with other elements to actually help produce a solid or liquid
