Need Latent Heat

    I just discovered that Oxygen can be presureized into Liquid Oxygen in TPT without using any cooling. However it lacks latent heat. If latent heat were implimented here's what would happen, and why.

    When O2 is compressed to the point it liquifies but no cooling is used, you are forcing it into a state of lower internal energy. That is a substance in its liquid phase has a low latent heat than its gas phase. By forcing it into this lower energy state without cooling it, you convert latent heat into a temperature increase (it releases the energy which had previously been stored by the very fact it was in its gas phase, and thus converts latent energy into thermal energy thus a temperature increase). By the same account when removing the high pressure source (VENT in my case) and allowing the pressure to escape it converts into a gas again. However this should (but it currently doesn't) result in the substance cooling, as it is forced into the gas phase by pressure change (not temperature increase) and therefore in order to increase its latent heat (the energy it stores by the very fact that it is a gas) as it becomes a gas, it must absorb heat from its environment, thus causing it to cool (converting thermal energy into latent energy causes a temperature drop).

    Therefore when pressurizing and depressurizing Oxygen and Liquid Oxygen in a way that forces a phase change, you should get a corresponding temperature change.

    Extra info, this is the same reasong that the temperature on the metal pipes on the outside of your refrigerator behind the unit are actually HOT. The compression is done outside, and the decompression is done inside of the refrigerator, with a substance that easilly changes between gas and liquid phases in response to pressure changes. So the extra heat from inside the fridge gets dumped outside the fridge. If latent heat were implemented, I can easilly see TPT being used to construct a realistic refrigerator (though using Liquid O2 isn't the same substance in a fridge, it would be the same principle).

    Problem. When the temperature changes LOXY will turn back into OXYG, or worse, combust, due to how the elements work.

    do you want lagtoy? then add it to a mod and it will lag under pressure :D

    terms of replying: this is a joke, anything lags under pressure, but this is seriously unneeded

    Well then make it so that it doesn't make too much heat. DUH!
