Hydrogen is a gas at room temperature. It is in the air that you breathe.

#### Explanation:

The boiling point of hydrogen is −252.879 °"C" at standard pressure.

To get hydrogen to the liquid state, the temperature must be below its critical temperature of $\text{33 K}$ or $- {240.15}^{\circ} \text{C}$ and must be at a minimum pressure of $\text{13 atm}$.
