Hydrogen is a gas at standard temperature and pressure.
Hydrogen peroxide is a liquid at room temperature, so its state of matter is liquid.
oxygen and hydrogen are a type of matter called gas
Hydrogen can exist in different states of matter depending on the temperature and pressure. At room temperature and pressure, hydrogen is a gas. At very low temperatures, it can become a liquid or a solid.
Hydrogen is considered matter because it has mass and occupies space. Matter is anything that has mass and takes up space, and hydrogen satisfies both of these criteria.
Potassium hydrogen tartrate is typically in the solid state at room temperature and pressure. It is a white, crystalline powder that is commonly known as cream of tartar.
Hydrogen peroxide is a liquid at room temperature, so its state of matter is liquid.
Hydrogen is a gas in normal conditions.

If it were a solid at room temperature, then that would be the state of matter. However, hydrogen is NOT solid at room temperature. It is a gas and that would be the state of matter.

The state of matter of hydrogen, which is the lightest element, is that of a gas at room temperature. Hydrogen also is very flammable gas.
Helium, hydrogen, and air are gases.
