Prepare for the Challenge
The Big Change
Physical Change
- No new substance is formed
- Usually reversible
- Example: Melting ice, cutting paper
Chemical Change
- A new substance is created
- Hard to reverse
- Indicators: Bubbles, heat, color change
States of Matter
Solid
Fixed shape, fixed volume. Particles vibrate in place.
Liquid
Takes shape of container, fixed volume. Particles slide past.
Gas
No fixed shape or volume. Particles move fast and far apart.
Mixing it Up
Heterogeneous
You can see the different parts! They are not evenly mixed.
Example: Trail Mix, Pizza, Sand in Water
Homogeneous
(Solution)
Perfectly mixed! It looks the same throughout.
Example: Lemonade, Salt Water, Air
Key Terms to Know
Density How tightly packed matter is in a space. (Mass / Volume)
Solubility The ability of a solute to dissolve in a solvent.
Sublimation Changing directly from a solid to a gas.
Viscosity A liquid's resistance to flowing (think honey vs. water).
Good luck on the Assessment!
