Which states are mixed?
Soda water holds a gas in a liquid. Can a solid mix with a gas?
Solid, liquid and gas are the three states of matter.
Step 1 of 3
- Three states, drawn as particles.
- Salt in water joins a solid and a liquid.
- Soda water joins a gas and a liquid.
Yes. Iron filings in a jar of nitrogen make one.
The rule
Each part of a mixture is a solid, liquid or gas. That is its state alone, at room temperature. Sort a two-part mixture by the states of its parts. Six pairs of states are possible.
| States of the two parts | A mixture of them |
|---|---|
| Solid and solid | Brass, from copper and zinc |
| Solid and liquid | Sugar stirred into water |
| Solid and gas | Iron filings in a jar of nitrogen |
| Liquid and liquid | Acetone, a nail polish remover, mixed with water in a cup |
| Gas and liquid | Soda water |
| Gas and gas | Helium mixed with oxygen in a tank |
Read each mixture. Drag or tap its two states into the jar.
