Study Notes
Properties of Matter
- Matter has four key properties: shape, mass, and volume.
- Mass is the quantity of matter in an object, while volume refers to the space that matter occupies.
States of Matter: Solids
- Solids maintain a definite shape, mass, and volume due to closely packed atoms.
- An example of a solid is a tree.
States of Matter: Liquids
- Liquids possess atoms that can move freely, allowing them to take the shape of their containers.
- Milk, when poured, will adopt the shape of any cup due to its liquid nature.
States of Matter: Gases
- Gases share the property of taking the shape of their container, similar to liquids.
- Atoms in gases are more spread out and move more freely compared to liquids.
Distinction Between Gases and Liquids
- Gases lack a definite shape and volume, allowing them to expand to fill their container.
- Liquids maintain a definite volume but change shape based on their container.
Examples of Matter
- Air is classified as a gas, not a liquid; it consists of freely moving particles.
- Oxygen is a type of gas, while examples of solids include a chair and wood.
Phase Changes
- Melting occurs when a solid, such as ice, transitions to a liquid state as its particles loosen.
- Water can exist as a solid (ice), liquid, or gas (steam) depending on temperature changes.
Compressibility
- Gases like air and oxygen can be compressed due to their lack of definite shape and volume.
- Solids, such as a tree, cannot be compressed because they have a definite shape and volume.
Volume Characteristics
- Only solids and liquids have a definite volume, while gases do not.
- Water, as a liquid, can be compressed but will not spread out infinitely like a gas.
Matter Composition
- Matter encompasses all substances that occupy space, including solids, liquids, and gases.
