# cooling by changing pressure... perhaps?

## Recommended Posts

in real life, the gas's volume, pressure and temperature are all connected. that means to cool a gas, you change its pressure and volume.

is this a feature in this game?

There's no pressure in the game. Only density, i.e. mass per tile.

For liquids (only) there's a thing resembling pressure damage on solid tiles, when the density of a liquid exceeds (by a lot) the natural one of the material. Water for example stacks a second layer above the first when above 1t per tile. IIRC, it's 740kg for petroleum.

There's no such a thing for gasses.

State change temperatures of elements are fixed, they don't change based on "pressure". The exception would be mass in pipes. Technically still not pressure, just the amount in a single segment of a pipe. But, when below 10% of the capacity of the pipe, not state change can happen.

So you can have 1kg of -270C water inside a pipe, without it turning solid and breaking the pipe.

You mean > 1kg.  <= 1kg and it won't turn to solid until it exits the pipe.  Likewise liquid water at 99C exposed to the vacuum of space won't boil.  And you can have literally unlimited pressure gasses that won't condense into liquid so long as they are above the boiling temperature.

No, I meant 'without' it...'. Corrected.

thanks for the answer! this explains a lot
