Study Notes
Properties of Matter
- Matter's characteristics are crucial for daily choices.
- Properties are categorized by scientists as physical or chemical.
- Physical properties describe matter without changing its identity.
Physical Properties
- Observing matter (seeing, touching, hearing, smelling, tasting) reveals physical characteristics.
- Physical properties aid in identifying substances.
- Unlike chemical properties, physical ones don't result in new substances.
- Examples include color, texture, odor, luster, clarity, and taste.
States of Matter
- The state of matter (solid, liquid, or gas) is a physical property.
- Solids have a definite shape and volume.
- Liquids have a definite volume but take the shape of their container.
- Gases have neither a definite shape nor volume; they fill their container completely.
Hardness
- Hardness measures resistance to scratching or denting.
- Diamond is the hardest known material.
- Materials vary in hardness; a harder material can scratch a softer one.
Malleability
- Malleable materials can be hammered or bent into different shapes.
- Aluminum foil and gold are good examples.
- Glass, conversely, is not malleable.
Ductility
- Ductile materials can be drawn into thin wires.
- Copper is a common ductile material, crucial for electrical wiring.
Melting and Boiling Points
- Melting point is the temperature at which a solid turns to a liquid.
- Boiling point is the temperature at which a liquid turns to a gas.
- These temperatures are characteristic physical properties.
- Water's melting point is 0°C and boiling point is 100°C.
Crystal Form
- Some solids crystallize in distinct, regular shapes (e.g., cubes of salt).
- Crystal structure is a physical property.
Solubility
- Solubility is a substance's ability to dissolve in a liquid (e.g., water).
- Solutes dissolve; insoluble substances don't.
- Salt dissolves in water, but pepper does not.
Viscosity
- Viscosity describes a liquid's thickness.
- Syrup is more viscous (flows more slowly) than water.
Density
- Density is the amount of matter per unit volume.
- Expressed in kg/m³ or g/cm³.
- Water has a density of 1.0 g/cm³.
Chemical Properties
- Chemical properties describe how a substance changes into a new substance.
- Reactions with other substances or with elements are key.
- Examples include flammability (ability to burn).
- Combustible materials react with oxygen to burn.
Combustibility
- Combustibility describes a substance's ability to react with oxygen and produce energy (light and heat).
- Flammable substances catch fire easily, like gasoline.
- Water and some materials are nonflammable.
