Study Notes
Matter
- Defined as anything that has mass and occupies space.
States of Matter
- Comprises three physical forms: solid, liquid, and gas.
Changing States of Matter
- Physical changes occur when matter transitions from solid to liquid and liquid to gas; these processes do not involve chemical changes.
Solids
- Characterized by a definite shape and volume, maintaining a fixed structure.
Liquids
- Possess a definite volume but do not hold a definite shape, adapting to the contours of their containers.
Gases
- Lack both a definite volume and shape, expanding to fill available space.
Boiling Point
- The temperature at which a liquid transforms into a gas.
Melting Point
- The temperature at which a solid turns into a liquid.
Diffusion
- Involves the movement of molecules from an area of higher concentration to an area of lower concentration.
Expansion
- Refers to the process of increasing size, volume, quantity, or scope.
Compression
- Describes a force that pushes or squeezes a material, reducing its volume.
Particles in a Liquid
- Molecules are free to move within a container while remaining in close contact with one another.
Particles in a Solid
- Molecules are tightly locked in place, allowing only limited vibration without free movement.
Particles in a Gas
- Molecules travel in straight lines until they collide with other objects, facilitating rapid movement.
Properties of Solids
- Exhibit definite shape and volume, a specific melting point, high density, incompressibility, and low rates of diffusion.
Properties of Liquids
- Feature relatively high density, relative incompressibility, ability to diffuse, and phenomena like surface tension, evaporation, boiling, and freezing; liquids flow easily.
Properties of Gases
- Display expansion, fluidity, low density, compressibility, and the ability to diffuse and effuse.
