Is oxygen a solid, liquid or gas?

Yes. At different temperatures and pressures it can be a gas, a liquid, or a solid. Along certain pressure-temperature combinations it can be a gas and a liquid or a liquid and a solid at the same time. And at a point called the triple point, it can exist in all 3 states simultaneously. read more

Oxygen has a melting point of 54.36 K (−218.79 °C, −361.82 °F) and boiling point of 90.19 K (−182.96 °C, −297.33 °F). Since room temperature is taken at 298K (25 °C, 77°F), and is greater than oxygen's boiling point, it exists as a gas at room temperature. read more
