After exhausting their core hydrogen, stars leave the main sequence and begin fusion in a hydrogen shell around the helium core and become giants on the red-giant branch. In stars with masses up to 2.3 times the mass of the Sun the helium core becomes a region of degenerate matter that does not contribute to the generation of energy. It continues to grow and increase in temperature as the hy… WebLiquid helium is a physical state of helium at very low temperatures at standard atmospheric pressures. Liquid helium may show superfluidity . At standard pressure, the chemical element helium exists in a liquid form …
WebAs we mentioned above, helium gas is not flammable. It is not explosive either. You can heat it up or cool it until it turns to a liquid (at below absolute zero) and it still won’t catch fire. Helium is one of the most stable elements, which means that it is not very reactive with other elements.
