Mmass of helium5/16/2023 ![]() ![]() ![]() If someone could either explain what I've missed or be willing to coauthor a paper disproving the fusion theory of star energy, I'd appreciate it.Įdit: Thanks, everybody. This is at odds with numerous sources that assert that fusion of hydrogen into helium releases 0.7% of the mass as energy. Thus, the outputs weigh more than the inputs. Outputs = 4 protons + 2 neutrons + 2 positrons + 2 neutrinos = 1.00421639 x10 -26 kg Mass of neutrino: smaller than rounding error, above. The mass of two neutrons + two protons, using the figures above = 6.695098 x10 27 kgīut: the mass of an alpha particle (which I gather is for all practical purposes, a Helium nucleus): 6.644657 x10 -27 kg The following figures come from Wikipedia, and presumably from some more reviewed source prior to that: Six protons combine over several steps to form:ġ helium nucleus, comprised of two protons and two neutrons. Helium is also available in bulk gas and liquid delivery, as well as in a full range of purities and tank sizes.I'm learning about the proton-proton chain. We offer helium in high-pressure gas cylinders and liquid dewars-available in a variety of sizes-to meet any and all low-volume needs. Mixed with argon, it’s also used to inflate airbags.įrom purging hydrogen systems to pressurizing fluid systems, helium is essential to aerospace and aircraft applications both in flight and on the ground. Helium is used to test for leaks and ensure quality in automotive parts like fuel tanks and radiator systems. Used for more than just filling balloons, helium is widely used in the retail industry in refrigeration systems. Also, helium’s low boiling and melting points make it ideal for cooling applications. Used as a carrier gas in gas chromatography, helium is essential for determining sample content and characteristics. In order to capture high-resolution imagery of internal organs and tissues, these machines use superconducting magnets that need liquid helium to reach the cryogenic temperatures at which they operate. Helium is essential for operating MRI and NMR machinery. In heat-treating processes, helium is added to furnace atmospheres to produce stronger, more durable parts. Helium is utilized for its inert properties such as providing ideal arc temperatures for welding materials with high-heat conductivity. Please contact an Airgas representative for a quote or more details about our variety of Heilum supply modes including Liquid Cylinders & Bulk deliveries.
