Test #1 Retakes – Schedule on front board

What method would I use to find the volume of a plastic toy “Agent P”? Why?

• What kind of math problem is required to find displacement?
• What metric units are used to represent mass?
• What are 3 equivalent formulas for finding the volume of a regular shaped object?
• What are 3 equivalent units for volume in the metric system?
• If you have 15 cc’s of H2O2, how many milliliters is this?
• What does dm stand for?
• What form of matter can be made up of a crystal lattice?
• Which form of matter is more energetic, plasma or gas?

### Summary

At the end of your Cornell Notes for Physical vs. Chemical:

1) Tell what the difference is between Physical & Chemical Changes…..or how can you determine whether a substance has gone through a physical or chemical change?

2) Why is density an effective way of identifying a specific type of matter?

Intro to Density

How tightly packed the particles are in a substance.

vs.

1. What is mass effected by?

A block of iron has very tightly packed compared to aluminum.

2. Will changing the volume change the density?

NO. Density is a RATIO between mass and volume….the particles remain packed the same way no matter what the size of the sample.

3. What are three ways to find volume?

• Use a G.C.
• bxh
• displacement

Yes. You will have more particles so mass will increase. BUT the density is the same.

vs.

4. Will changing the volume change the mass?

Finding Volume
• The length is 3 cm the width is 4 cm and the height is 5 cm.
• The length is 4 dm, the width is 6 dm and height is 9 dm. The volume is?
• The length is 10 m, the width is 4 meters the height is 7 meters. The volume is?
