it is a gas
Liquid helium is very cold, with a boiling point of -268.9°C. When exposed to room temperature (~20°C), the thermal energy causes the liquid helium to rapidly boil and transition into a gas state.
At room temperature, helium, neon, and krypton are gases. Radon is a radioactive noble gas that is also a gas at room temperature.
Helium is a noble gas at room temperature, and exists as a colorless, odorless gas. Helium becomes a liquid at very low temperatures, about -269 degrees Celsius, and a solid at an even lower temperature of around -272 degrees Celsius.
Under standard conditions of pressure and temperature Helium is a gas.

It is a gas.Answer:Helium can be in any state (solid,liquid or gas) depending on its pressure and temperature. At 2.5 MPa:Below -272.20oC it is a solidAbove -268.93oC it is a gasBetween these two temperatures it is a liquid

Helium can exist in both liquid and gas states. At extremely low temperatures, around -269°C, helium can turn into a liquid. This makes helium unique among the elements, as it can exhibit both fluid behaviors as a liquid and gas.
