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.
