WebJun 23, 2024 · Helion’s fuel of deuterium and helium-3 burns at just 200 million degrees, achieved using plasma rings similar to TAE’s but compressed with magnetic fields. But helium-3, although stable, is nearly as rare and hard to acquire as tritium. Most commercial sources of it depend on the decay of tritium, typically from military stockpiles. WebDec 18, 2024 · The size-comparison between helium and dihydrogen is straightforward: Dihydrogen is larger. As for the strength of interparticle interactions, we can compare normal boiling points: Helium's is 4 Kelvin and dihydrogen's is 24 Kelvin. So this would suggest that helium is "more ideal" as it has the lower boiling point and the smaller size.

WebMar 9, 2016 · Humans, wishing to understand how different types of matter behave chose to create a system of three states. This choice is the key: the reason "matter exists in 3 states" is because we chose to model it that way. It would be trivial to declare "matter exists in 5 state" or "matter exists in 2 states."

WebDec 10, 2024 · Neither helium-3 nor helium-4 can become solids at atmospheric pressure. Instead, they become solids at 20-40 atmospheres. In the perspective of quantum mechanics, helium is the second simplest atom to model, following the hydrogen atom. Helium is composed of two electrons in atomic orbitals surrounding a nucleus containing two protons and (usually) two neutrons. As in Newtonian mechanics, no system that consists of more than two particles can be solved with an exact analytical mathematical approach (see 3-body problem) and helium is no exception. Thus, numerical mathematical meth… WebIt exists as a gas, except under extreme conditions.
