A simple equilibrium simulation of water evaporating into a vacuum from a liquid phase. The simulation shows the eventual "equilibrium" reached which is a perpetual balance between phases. The simulation is mainly a teaching aid and is not an accurate simulation. It's purpose is to illustrate the general idea of equilibrium. The simulation uses Coulomb's Law to approximate Van der Waals forces and Hooke's Law to approximate bond energy vibration. Other algorithms were also used to make it visually appealing.
