Hydrogen's physical state at room temperature is a gas.
Hydrogen is a gas at room temperature.
At room temperature, hydrogen is in the gaseous phase.
Hydrogen bromide (HBr) is a gas at room temperature.
Gas at room temperature.
The element hydrogen is in the gas phase at standard temperature and pressure.
At room temperature, hydrogen is a colorless, odorless gas. It is the lightest and most abundant element in the universe. Hydrogen becomes a liquid at very low temperatures, below -252.87 degrees Celsius.
At room temperature, hydrogen is a colorless, odorless, and tasteless gas. It is the lightest and most abundant element in the universe. Hydrogen molecules consist of two hydrogen atoms bonded together (H2).
They are gases at room temperature.
Hydrogen's normal phase is a gas at room temperature and pressure.
No. Hydrogen is a nonmetal and a gas 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.
