Product Description

Product Description

Helium gas is a colorless, odorless, and tasteless gas that belongs to the noble gas group on the periodic table. It is the second lightest element, after hydrogen, and has the atomic number 2. The symbol for helium is He.

Properties of Helium Gas:

• Density: Helium is much lighter than air, with a density approximately seven times less than that of air.
• Boiling Point: Helium has a very low boiling point of -268.93 degrees Celsius (-452.07 degrees Fahrenheit), which is only slightly above absolute zero.
• Melting Point: Helium has an even lower melting point of -272.2 degrees Celsius (-457.96 degrees Fahrenheit).
• Non-reactive: Helium is chemically inert, meaning it does not readily react with other elements or compounds under normal conditions.
• Low solubility: Helium is practically insoluble in water and most other common solvents.
• Low viscosity: Helium has very low viscosity, which means it flows easily and does not create significant resistance to motion.

Uses of Helium Gas:

1. Balloons: Helium is commonly used to fill balloons due to its low density. The gas makes balloons float in the air.
2. Cryogenics: Helium is used in cryogenics to achieve extremely low temperatures for various applications, such as in cooling superconducting magnets in MRI machines and particle accelerators.
3. Welding: Helium is used as a shielding gas in arc welding to protect the weld area from atmospheric gases, preventing oxidation and ensuring cleaner welds.
4. Leak Detection: Due to its low viscosity and ability to diffuse quickly, helium is often used as a tracer gas in leak detection for various systems, including pipelines, tanks, and refrigeration systems.
5. Deep-sea Diving: Helium is used in diving gas mixtures for deep-sea diving to prevent nitrogen narcosis, also known as "rapture of the deep."
6. Research and Scientific Applications: Helium is utilized in various research fields, including in cryogenics, nuclear physics, and as a carrier gas in gas chromatography.

It's worth noting that helium is a finite resource on Earth and is primarily obtained as a byproduct of natural gas extraction. Due to its scarcity, conservation and responsible usage of helium are essential.
