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

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

Tell how you can separate saltwater, trail mix, sand with iron filings. Lesson 2-1

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

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

Example:___________________ 4. Electrical conductivity is the ability of matter to conduct electric current. Example:___________________ 5. Thermal conductivity is the ability of a material to conduct thermal energy. Example: ______________________ 6. Solubility is the ability of one substance to dissolve in another. Example: Salt & water; oil & water Lesson 2-1
