Study Notes
Physical Properties
- Defined as features of matter that can be observed without altering the identity of the material.
- Examples include color, density, conductivity, smell, malleability, melting point, taste, ductility, boiling point, texture, solubility, and magnetism.
Malleability and Ductility
- Malleability refers to the ability of a substance to be flattened or stretched without breaking; metals exhibit high malleability.
- Ductility is the ability of a substance to be stretched into a wire.
Solubility
- Solubility is the measure of how well one material dissolves in another, influenced by temperature, stirring, surface area, and the amount of solute.
- A solute is the material that is being dissolved, while a solvent is the substance that does the dissolving.
Examples of Solvent and Solute
- In chocolate milk, milk acts as the solvent and chocolate syrup as the solute.
- In tea, hot water serves as the solvent and tea leaves as the solute.
Other Physical Properties
- Magnetism relates to how well a substance adheres to a magnet.
- Thermal conductivity indicates how effectively heat travels through a material.
- Electrical conductivity measures how well electricity flows through a substance.
- Melting point is the temperature at which a solid becomes a liquid; boiling point is where a liquid transforms into a gas.
- Characteristic properties, such as density, melting point, and boiling point, remain constant regardless of the quantity of substance.
Chemical Properties
- A chemical property describes the ability of a pure substance to undergo chemical changes, resulting in new substances.
- Examples include flammability, which assesses a material's ability to react with oxygen to produce heat or flame, and reactions with acids, which may produce bubbling or hydrogen release.
Non-reactivity
- Non-reactivity refers to the inability of a substance to undergo a chemical reaction.
Chemical Reactions
- Chemical reactions typically produce new substances and are usually irreversible.
