Everything around us exists in one of three states of matter: solid, liquid, or gas. Water is special because it can easily change between all three! This worksheet will help you learn the differences between these states and how water transforms from one to another. Think of ice (solid), the water you drink (liquid), and steam from a hot shower (gas)!
Match each term with its definition:
| Term | Definition |
|---|---|
| 1. Evaporation | A. The state of matter with a fixed volume and shape. |
| 2. Condensation | B. The process of a liquid turning into a gas. |
| 3. Solid | C. The state of matter with a fixed volume but no fixed shape. |
| 4. Liquid | D. The process of a gas turning into a liquid. |
| 5. Gas | E. The state of matter with no fixed volume or shape. |
Complete the paragraph using the words: melting, freezing, liquid, gas, solid.
When ice, which is a ________, warms up, it goes through ________ and turns into water, which is a ________. If the water gets even hotter, it turns into steam, which is a ________. The opposite of melting is ________.
