States of Matter and Solubility

Flashcards covering key vocabulary related to states of matter and solubility concepts.

Solid

A state of matter that holds its shape and has a fixed volume.

Liquid

A state of matter that takes the shape of its container but has a fixed volume.

Gas

A state of matter that takes the shape and volume of its container.

Evaporation

The process by which a liquid turns into a gas.

Condensation

The process by which a gas turns into a liquid.

Sublimation

The process of a solid turning directly into a gas without becoming a liquid first.

Diffusion

The process by which particles spread from an area of high concentration to an area of low concentration.

Kinetic Theory

A theory that states all molecules or atoms in a fluid are in constant, random motion.

Brownian Motion

The random motion of very small particles suspended in a fluid, observed under a microscope.

Solubility

The ability of a substance to dissolve in a given amount of solvent at a specific temperature.

Solvent

A substance that dissolves a solute to form a solution.

Solute

A substance that is dissolved in a solvent.

Solution

A homogeneous mixture composed of two or more substances.

Saturated Solution

A solution that cannot dissolve any more solute at a given temperature.
