Study Notes
Matter and Its Properties
- Matter is any substance that possesses mass and occupies space (volume).
- Mass quantifies the amount of matter in a substance or object.
- Volume measures the amount of space a substance or object occupies.
Properties of Matter
- Properties help describe and identify substances, divided into physical and chemical properties.
- Properties can further be classified as intensive (independent of the amount of substance) or extensive (dependent on the amount).
Physical Properties
- Physical properties can be observed or measured without changing the substance into a different form.
Chemical Properties
- Chemical properties involve the transformation of one kind of matter into another, indicating how a substance reacts under certain conditions.
Physical Changes
- Physical changes affect a material's appearance without altering its composition.
- Melting point and freezing point are equivalent; energy removal leads to freezing, while energy addition leads to melting.
Energy Processes
- Endothermic processes involve the absorption of energy, causing temperature rise.
- Exothermic processes entail the release of energy, resulting in temperature drop.
Chemical Changes
- Chemical changes result in the alteration of the composition of matter, creating new substances with different properties.
