Oxygen is a gas at room temperature.
Oxygen is typically found in the gaseous state at room temperature and pressure.
gas liquid and solid
Oxygen can be liquid or a gas. It is just a different state of matter.
Oxygen at -250 degrees Celsius would be a solid.
Under normal condition-it's gas
At a temperature of 20 degrees C (or F, for that matter) 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.
Just as in all the other answers to this question, it is normally a gas. It can be liquefied .
No, a gas is a state of matter. oxygen can be found in either liquid or gaseous states
