Air is always a gas.
Potassium can be solid, liquid or gas. At normal room temperature and atmospheric pressure it is a solid. Above 63.3oC it is a liquid and above 760oC it is a gas.
It is a solid
gas
Solid in solid: metal alloys. Liquid in liquid: vinegar dissolving in water. Gas in gas: air. Solid in liquid: salt dissolving in water. Liquid in solid: mercury absorbed by gold. Gas in liquid: carbon dioxide dissolving in soda. Solid in gas: smoke particles in air. Liquid in gas: water vapor in air. Gas in solid: hydrogen absorbed by palladium.
Air is a gas at room temperature, and well below it, too. This can be observed in any footage of explorers in arctic or antarctic situations. The gases in air, at least the primary ones, which are nitrogen and oxygen, don't liquify until hundreds of degrees below zero.
air is neither liquid or solid, it is a gas

Solid (such as metal) Liquid (such as water) Gas (such as air)
the buoyant force of the liquid on the solid is more than the buoyant force of the air on the solid.
as a liquid and solid it is not - as a gas I suspect not although I'm not sure
It is a solid
Praseodymium is a metallic solid at room temperature. The melting point is 935 degress Celcius.
No, it is a solid.
gas
It means whether the substance in question is solid, liquid or gas at normal room temperature, so you could assume that about 20 degrees celsius. Oxygen is a gas at room temperature Water is a liquid at room temperature Iron is a solid at room temperature.
its neither. Air is a gas
It is a solid metal. Incredibly reactive in water.
