States of matter Model The different states of matter can be demonstrated by the development of several models. One model that is most effective in demonstrating the properties of each state is outlined below. Material: Drill 1m metal rods 20 polystyrene balls Thick wooden base Thin plywood to act as a slider as shown on the right. Place the slider and the wooden base on top of each other. Drill 20 holes through the slider and into the thick wooden base as shown on the right. Attach the metal rods so that they are firmly held in position. Place the polystyrene balls at the ends of the metal rods as shown on the right. When the slider is pushed to the top, the balls are held together firmly and move about as a unit. This simulates the particles of a solid. But when the slider is pushed right to the bottom the balls move about independently at high speeds when the metal rods are shaken. This simulates the particles of a gas. Shaking the metal rods indicates energy input in the form of heat. Moving the slider somewhere in the middle causes the balls to move about while remaining close to each other, simulating the particles of a solid.

As the slider moves from top to bottom it represents an increase decrease in temperature. In the gas state, the more energy given to the particles the greater their size speed From our model, we can conclude that particles in a solid gas liquid have more energy than the particles of a liquid solid gas which in turn have more energy than the particles in a solid gas liquid .
