Study Notes
Properties of Matter
- Matter can be classified into two categories: physical properties and chemical properties.
- Physical properties can be observed without changing the chemical composition of the matter.
- Physical properties can be further divided into intensive and extensive properties.
-
Intensive Physical Properties are independent of the amount of matter. Examples include:
- Color
- Shape
- Temperature
- Malleability (ability to be hammered into thin sheets)
- Ductility (ability to be stretched into thin wires)
- Diffusion (ability to spread out)
-
Extensive Physical Properties are dependent on the amount of matter. Examples include:
- Size
- Mass
- Volume
- Density
- Length
- Width
-
Chemical Properties describe how a substance reacts with other substances. Examples include:
- Combustibility (flammability)
- Oxidation (such as rusting)
-
Examples:
- Color and taste are intensive physical properties
- Rusting is a chemical property
Measuring Physical Properties
- A measuring tape can be used to measure length, which is an extensive physical property.
- A graduated cylinder can be used to measure volume, which is also an extensive physical property.
Identifying Materials:
- Copper wires are often used for electrical wiring because copper is ductile (can be stretched into wires).
- Materials that easily break when force is applied are brittle.
- Wood is a poor conductor of heat.
Activity 1- Testing the Properties of Matter
- The activity involves observing the physical and chemical properties of: salt, sugar, water, cooking oil, and tissue paper.
- Mass
- Color
- Taste
- Flammability
- The activity aims to help students understand the differences between intensive physical properties, extensive physical properties, and chemical properties.
