Write a short essay in which you create an analogy to describe particle motion. compare the movements and positions of people dancing with the motions of water molecules in liquid water and in water vapor.

Particle motions can be compared to people movements in a dance.  Ballroom dancing is a dance where everyone has a partner and the groups dance on one large stage, much like liquid water in a container. Water particles in this state stick with each another by Hydrogen bond; just like couples move in a ballroom dance.

Particles move more freely in water vapor, colliding with each other sometimes, such as the dance movement in freestyle dancing. Freestyle dancing is basically making up dance movements to a song on the spot with no previous choreography, where dancers each have their own individual dance. In water vapor it is the same thing because as a gas it moves in all different directions and each particle goes its own separate way.
