It is a gas.
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.
Helium, hydrogen, and air are gases.
H2 is a molecule composed of two hydrogen atoms and is in the gaseous state at room temperature and pressure.
the state of matter of chromium is a solid
Iron is surely a solid at room temperature.
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.
Hydrogen peroxide is a liquid at room temperature, so its state of matter is liquid.
Hydrogen's physical state at room temperature is a gas.
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.
oxygen and hydrogen are a type of matter called gas
Gas at room temperature.
At room temperature, hydrogen sulfide exists as a colorless gas with a characteristic foul odor of rotten eggs.
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 can exist in different states of matter depending on the temperature and pressure. At room temperature and pressure, hydrogen is a gas. However, at very low temperatures, hydrogen can become a liquid, and at extremely high pressures, it can solidify into a metallic state.
Helium, hydrogen, and air are gases.
H2 is a molecule composed of two hydrogen atoms and is in the gaseous state at room temperature and pressure.
They are gases at room temperature.
