Hydrogen for cooling?

[Reformed Automatan]

I have heard that hydrogen is really good or base cooling, is this true, and if so how and why does it work?

Grind This Game has some good tutorials for explaining things like that.

The jist of it is, Hydrogen has the highest Specific Heat of all the gasses at I think 2.4 J/kg/K meaning it takes the most energy to change its temperature. That is quite a bit higher than any of the other gasses.
Certain mechanics change the temperature of gasses by a set amount and ignore that specific heat value. Not sure if these are the right values but Wheezeworts change temperature by 12°C and the gas HVAC thing is set at 14°C.
And of course you can just dump Hydrogen into the Anti-Entropy devices.

So basically you use hydrogen in high thermal conductivity ventilation pipes, or sit hot equipment in a high hydrogen atmosphere. The hydrogen absorbs more energy than any other gas (because heat transfer is a function of difference in temperature and hydrogen will stay cooler for longer), then you use those items to essentially remove more heat energy than any other gas.

It is because Hydrogen can get very cold before it liquifies (-252 C), and it has (for a gas) a high thermal conductivity, so it will collect heat (or "radiate cold") more easily than other gasses.

Edit: Plus the specific heat thing Evilsod mentioned.

To put it simple, it stores a good amount of heat energy (cold being one) and releases it better then other gases.

Hydrogen is good for cooling any non liquid area since it has the lowest temperature range before it liquidifies.

But if your trying to cool liquids, co2 is king since you can freeze it to a solid which allows it to interact with any liquid under it near the heat nullifer.
