States of Matter, Solids, Liquids and Gasses

Boiling

The vaporization of a liquid. Boiling. Boiling is when a liquid turns into a gas at its boiling temperature, forming bubbles.

Boiling point

The temperature at which a liquid boils. Boiling point. The boiling point is the temperature at which a liquid turns into a gas.

Boyles law

States that pressure increases when volume decreases, and vice versa, if the gas temperature is constant. Boyle's Law. In simple terms, Boyle's Law explains how if you squeeze a gas into a smaller space, its pressure goes up, as long as the temperature stays the same.

Charles law

States that when gas pressure is constant, its volume increases with temperature, gases expand when heated. Charles law. Charles's Law describes how gases expand when heated at constant pressure.

Condensation

The process of a gas changing into a liquid is called condensation. Condensation is when water vapor in the air cools down and turns back into liquid water.

Evaporation

The top of liquid changing into a gas. Evaporation. It's the process where liquid turns into gas, usually on the surface when it gains enough energy.

Gas

A state of matter that has no fixed shape or volume. Gas. Gas is a substance composed of particles that move freely and can expand to fill any container.

Liquid

A state of matter that has definite volume but no definite shape. Liquid. Liquids flow and take the shape of their container while maintaining a consistent volume.

Melting point

The temperature at which a solid changes into a liquid is the melting point. It's the specific temperature at which a solid turns into a liquid.

Solid

The state of matter with definite shape and volume solid. A solid is something that keeps its shape and does not flow like a liquid or gas.

Sublimation

The change of state from a solid directly to a gas. Sublimation. Sublimation is when a solid turns into a gas without first becoming a liquid.

Surface tension

The force acting on particles at the surface of a liquid surface tension. Surface tension is the effect where the surface of a liquid acts like a thin, stretchy skin due to the attraction between its molecules.

Temperature

How hot or cold something is, it is determined by the kinetic energy of its particles. Temperature. Temperature is a measure of how fast the particles in a substance are moving.

Vaporization

The change of state from liquid to gas. Vaporization. Vaporization is when a liquid turns into gas, like when water boils and becomes steam.

Viscosity

A fluid's resistance to flowing. Viscosity. Viscosity is how thick or sticky a fluid is, affecting how easily it flows.
