materials that undergo changes

1. Changes materials that undergo (grade 3)

2. 3 TYPES OF MATTER Solid A solid is a state of matter where particles are tightly packed together and have a fixed shape and volume. For instances: ice, wood, and metal Solid, Liquid, gas

3. Liquid A liquid is something that can pour and take the shape of its container, like water or juice. Gas A state of matter that spread out to fill its container. Example include air, helium, and steam.

4. Changes of Matter The transition from solid to liquid sate is called melting. This occurs when the solid’s particles gains enough energy to overcome their attractive forces and move freely, resulting in a change in shape and volume. For example, when chocolate bar (solid) is heated, it melts into a liquid form. A. From Solid to Liquid

5. Boiling, condensation, and evaporation: evaporation is a change of a substance from a liquid to a gas. Boiling is change of a liquid to a vapor, or gas, throughout the liquid. Condensation is the change of state from a gas to a liquid. B. From Liquid to Gas Evaporation example: wet clothes drying in the sun. Boiling example: pressure cookers. Condensation example: a foggy mirror.

6. Freezing occurs when a liquid is cooled and turns to a solid. Eventually the particles in liquid stop moving about and settle into a stable arrangement, forming a solid. This called freezing and occurs at the same temperature as melting. C. From Liquid to Solid

7. D. From Solid to Gas the process in which solids directly change to gases is known as sublimation . This occurs when solid absorb enough energy to completely overcome the forces of attraction between them. Dry ice is an example of solids that undergo sublimation
