Under standard conditions of pressure and temperature Helium is a gas.
there are no states of matter in helium.helium is a gas,wich is a state of matter.
it is a gas
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.
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 at room temperature and pressure. It can be liquefied at very low temperatures (-269°C) and becomes a liquid at that point. Helium does not exist in a solid state under normal conditions.

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
