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
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
