Above -268.93 °C, helium is gas. Below -268.93 °C, helium is liquid.
Helium cannot exist as solid.
there are no states of matter in helium.helium is a gas,wich is a state of matter.
it is a gas
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)
When you heat a liquid and it changes phase it becomes a solid.
Yes, petroleum freezes solid at a sufficiently low temperature. In fact, there is only one substance which does not have a solid phase, which is helium. Helium exists only as a gas or a liquid. But everything else will freeze if sufficiently cooled.

Helium is a gas, belonging to noble gases (group 18)
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
All material things (except helium ... no solid form known - yet).
Covalent.Every compound can exist as a solid, liquid, or gas, given the right temperature and pressure. This is also true of every element, with the single exception of helium, which has no solid phase, no matter how cold it is. Helium is unique.

When you heat a liquid and it changes phase it becomes a solid.
helium is a gas less dense than air.
