“All things are made up of atoms.”
States of matter
Solid, liquid, gas, and plasma
State of Solids
- Has definite shape and volume
- High density and not very compressible
- Does not depend on the shape of the container (doesn’t fill it in)
State of Liquids
- Has a fixed volume
- Takes the shape of container
- Less dense than solids
- Almost incompressible
State of Gases
- Takes the shape of the container
- Takes the volume of container (this means that the gas molecules can be spread out evenly in the container or compressed in a smaller container. The volume is when the molecules are evenly distributed.)
- Can be compressed
- Gases are in the gaseous state at room temperature
- Gases have more energy than liquids, and solids.
- Gases are less dense.
State of Plasma
Plasma is simply an ionized gas, where the gas is charged with free electrons and positive ions because of the amount of energy plasma contains.
