Particle System Source Code for Water Molecules under Heat - Beginner Friendly

[Foam]

Can you give me source code for water molecules under heat ?
Source code can be of any programming languages..
Its not necessary water molecule, any particle system for beginner is also fine
I highly appreciate your help.

Thank you in advance

You need to reform your question. It makes no sense as its stated. Source code to do what?

I think water molecules if heated will run in different direction and I like to modelling the 100C molecules, they fly out of the boiling soup, something like that ?

Have you write any program like that before, can you give me source code ?Thank you
