Usage

Helium is the only monoatomic gas in-game, giving it an unrivaled heat capacity ratio of 1.666666. This, along with its low molar mass, give make it ideal as a pressurant in specialized rocketry applications where Hydrogen isn't suitable.

It is also completely inert, being incapable of condensing into a liquid form. This allows its use as a non-phase-changing heat exchange medium in extremely low temperature applications.
