At room temperature, oxygen is a gas.
Oxygen is an element and can be in all of the listed phases however oxygen is normally a gas (that you breath) under normal temp. and Pressure. Oxygen can be liquified if cooled past its boiling point. Furthermore it can become a solid if cooled past its melting point. short answer: Oxygen can occur in all three states but is normally a gas
As it occurs in the Earth's atmosphere, the oxygen molecule is a gas. However it can be a solid, liquid, or a gas, depending on the temperature and pressure in which it is found.
Oxygen can be any of the three. However at standard temperatures and pressures, it presents as a gas.
At STP, oxygen is a gas.

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
Oxygen is a gas (in both forms: O2 and O3) at normal pressure and temperature.
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.
