The States of Matter
A Science Presentation by Mrs. Saysana
There are three states of matter. Solids, liquids and gasses.
Solids have a definite shape and a definite volume. The particles that make up a solid are closely packed together and move slowly.
A liquid has a definite volume, but no definite shape. Liquids take the shape of whatever container they are poured into. The particles of a liquid have more energy than those in a solid, and they aren't as closely packed.
Gasses have no definite shape or volume. They expand to evenly fill the space of whichever container they are in. The particles have more energy than in a solid or liquid, and they are spread out.
