Nitrogen weighs 1.2506 grams per liter, while helium only weighs 0.1785 grams per liter. When helium is pumped into a balloon, it displaces the heavier air, so the pressure and temperature around the balloon push it upwards. Another cool science fact behind helium is its ability to change from a gas to a liquid or even a solid.

Facts about Helium - Introduction One liter of liquid helium expands to 750 liters of helium gas under normal or also called standard conditions (1 bar, room temperature), when going through the boiling point of 4.2 K.

Star Power. In the inner region of a star, four hydrogen atoms are converted into one helium atom. The sun converts 600 million tons of hydrogen each second, creating 400 million tons of helium. Helium Fact Sheet .

Helium is an extremely versatile gas due to its favourable physical and chemical properties. Find out more at the uses of helium at BOConline UK.

At 25 atmospheres of pressure helium is a solid at 0.95 K. As the pressure rises, the temperature at which solid helium exists also rises. Helium can be made solid at room temperature if the pressure rises to about 114 thousand atmospheres: that is a pressure of 1.67 million psi, or 834 tons per square inch.

Helium is a noble Helium is extracted from natural gas. In fact, all natural gas contains at least trace quantities of helium. The fusion of hydrogen into helium is the sources of a hydrogen bomb's energy. Helium is a disintegration product of radioactive substances, so it is found in ores of uranium, radium, and other elements. There’s a lot more to this element, so here are a few facts to get you started: 1. Helium is one of the most abundant elements in the universe. As one of the most abundant elements in the universe – clocking in as the second-most-widespread element on Earth – helium gets around.
