1. Common physical properties:
State of Matter
Mass
Volume
Density
Conductivity
Solubility
Magnetism
Boiling/Melting Point

2. The parts of a mixture often can be separated by physical properties
A physical property is a characteristic of matter that you can observe or measure without changing the identity of the matter.
The parts of a mixture often can be separated by physical properties
See next slide for 3
Lesson 2-1

3. 3. Consider the chart below then tell how you can separate saltwater, trail mix, sand with iron filings.
Lesson 2-1

4. Mass and volume are size-dependent physical properties; their values depend on the size of a sample.
Density is size-independent physical property because it will be the same regardless of the sample size. …
Lesson 2-1

5. What other points does the apply for also?
3. The boiling point of water is 100°C at sea level. The boiling point does not change for different volumes of water.
What other points does the apply for also?
Lesson 2-1
