1. Matter Review
Physical Science

2. Anything with mass and volume
Not chemically
combined
Two or more elements chemically combined
Atoms
Build these
Atoms are the building blocks of all matter!
Same Throughout
*Solutions*
Different Throughout
* Easily separated*

3. What makes each state of matter different is how tightly the particles are held and how much energy there is.

4. We use properties, a trait that matter possess, to help us classify various types of matter.

5. Chemical Changes:
Did it turn into something new?
Physical Changes:
Did it just change appearance yet is still made of the same thing?

6. Phase Changes are Physical Changes

7. Temperature: A measure of the kinetic energy of molecules

9. A rock has a mass of 50 g and a volume of 5 mL, what is its density?
Density= Mass/Volume
Volume= l x w x h
A rock has a mass of 50 g and a volume of 5 mL, what is its density?
An object has a mass of 20 g and its density is 10 g/mL, what is its volume?

10. The object in the diagram to the left has a mass of 100 g
The object in the diagram to the left has a mass of 100 g. What is the object’s density?
If the object to the left has a density of 2.08 g/cm3, what must its mass be?
