What Are Physical Changes In Matter 1
- 1. What are Physical Changes in Matter? Lesson #2
- 2. States of Matter Three States of Matter -solid -liquid -gas -Every substance on Earth can exist as a solid, as a liquid, or as a gas. -The difference between them is in the way the particles move. Example: Water
- 3. Solid Particles are close together (do not move) and just vibrate in place.
- 4. Liquid Particles that are close to each other, but also they move quickly and slide past each other easily.
- 5. Gas Particles are far apart and moving really fast.
- 6. 4 Ways Substances Can Change State change of state -occurs when a substance changes from one another. Each change of state has its own name. solid to a liquid liquid to a gas gas to a liquid liquid to a solid -melting -boiling -condensing -freezing
- 7. Physical Changes physical change- is a change that does not result in a new substance. Examples of Physical Changes -cut, rip, fold, crumple, shred, carve, etc… (also changes in state- melting, freezing, boiling, and condensing) In a physical change, no new substance is formed. Example- If you shred paper. What is left? (paper) What you started with is what you ended with!
- 8. Mixtures In science, mixtures have a specific definition which is two or more substances that combine without changing any of them . Example: salad, vegetable soup, soil, lemonade, chocolate milk, etc… -Not all mixtures are made of solids, but most materials are found in nature. -Remember being in a mixture DOES NOT change the substance and mixtures can be separated back out.
