States of Matter and Particle Motion Tutorial

Matter Matter is anything that has mass and volume. There are three main types of matter. They are solid, liquid, and gas.

States of Matter The state of matter is determined by the movement of particles within the matter. Solids LiquidsGases

Particle Motion of Solids There are two basic types of particle arrangement in solids: crystalline and amorphous The particles in solids don’t move much, but they do vibrate slightly. Notice how the solid maintains its shape in the container.

Crystalline vs. Amorphous Solids Crystalline Solids The particles in a crystalline solid are arranged in a repeating pattern. Amorphous Solids The particles in an amorphous solid are arranged randomly.

Particle Motion of Liquids The particles in liquids slide past one another. As you can see, a liquid will take the shape of its container.

Particle Motion of Gases Gas particles move fast and strike one another. Gases spread out to fill their container.
