Heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .

The process described is called freezing.  Any substance in its solid state is frozen.  We tend to think of things that are frozen as being cold because ice tends to be our frame of reference.  However, a ball of solid steel sitting on table in hot garage in August is a ball of frozen steel because steels freezing point is much higher than water's freezing point.  The freezing temperature depends on the properties of the elements in the substance.  Some substances freeze at cold temperatures (water), some substances freeze at really cold temperatures (carbon dioxide, nitrogen), and some temperatures freeze at hot temperatures (steel).
