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:
Gas at room temperature (298 K)

Under standard conditions of pressure and temperature Helium is a gas.
Helium is a gas.

At room temperature, it is a gas. When cooled to within a few degrees of absolute zero, it is a liquid.
Helium is a gas at room temperature.
Gas at room temperature (298 K)
Gas
Above -268.93 °C, helium is gas. Below -268.93 °C, helium is liquid. Helium cannot exist as solid.

Helium is a gas, belonging to noble gases (group 18)
helium is a gas less dense than air.
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

No, it is a gas-solid mixture when view as a whole. It has a solid component (the balloon itself), and a gas component (the helium)
Helium is a gas because its density at room temperature under one atmosphere of pressure is so low that the atoms do not form a liquid or solid.
