Pressure and Melting

[blash365]

I would like to point out that the game might still have some potential in treating temperature of materials under different pressure.

 

At absolute zero the molecules (or parts of molecules) of an element are absolutely frozen in position. When temperature rises, they gain kinetic energy and start moving. The more temperature, the more active they become and since every molecule has neighbouring molecules, they will start colliding (or simply pushing each other away) dampening the temperature again.

Only when more and more energy is put into the system, the kinetic energy will be able to increase (and thus temperature) without being limited by the neighbourhood.

That is unless the pressure of the element decreases. The lower the pressure in the environment, the bigger the distance to the neighbouring molecules, the easier it is to gain temperature.

 

In other words: Higher pressure water should take more heating to vaporize than low pressure water.

As a matter of fact, it is even possible to create steam out of water by simply placing it in a vacuum at room-temperature.

 

If someone with more knowledge of thermodynamics wants to follow up, i'd be delighted.

Right now its much easier to vaporize up droplets of 1-10 kg of water than a whole cube of water... seems its implemented by now. 

Otherwise implementing pressue will be much more cpu intense on a game that cannot allow itself to be cpu intense.

And I again agree! The game needs this physics! Heat rises, warm gases and liquids rise, but do not expand? And yes, we need compressors to change pressure of substances and making thermodynamic cycles.

 

Vovik, no, it will not cause cpu intense! No more than chaotically moving gases now.

How do you expect warm gases expanding in a tile-type enviroment?

[Rusjcd]

Vovik, The same way that they already are. If you add some more oxygen in closed area with carbon dioxide, oxygen will compress the dioxide to less value, to less tiles. So, the same value of heated oxygen should compress not heated dioxide.

 

BTW, personally, I want this to control temperature, not for visible effect. Compressing gas - It becomes colder and gives off heat outside.

Heating a mass to a certain temperature does of course take less energie than heating up _more_ mass to the same temperature (if no other variable changes).

 

My point is that if the pressure variable changes (same mass), it should use less energy with less pressure.
