In a solid the particles move the least, however, in a gas the particles move the most. In the right conditions, when solid particles meet liquid particles they can mix together to form a special mixture called a solution. This process is called dissolving.This process doesn't happen when any solid or liquid meet (your glass doesn't dissolve when you put water in it) only when the right solid meets the right liquid. When they do dissolve, the solid part is called the solute and the liquid it dissolves in is called the solvent.hen you put some sugar in your coffee you want the solid sugar to dissolve in the liquid coffee to give a sweet solution.
