what does this MEAN

Well you see, helium and nitrogen both have expansion ratios of about 700. Thus, when working with cryogenics, it's important to safeguard against oxygen depletion in the vicinity - a ruptured dewar can completely flood smaller areas' atmospheres with unbreathable gas.

As for why cryogenics work is being done on your page? Well dont worry about it 🦊👍
