States of Matter and Properties

Flashcards covering key concepts related to states of matter, changes in states, and properties of matter.

Solid

Particles are tightly packed and do not move around.

Liquid

Particles are close together, vibrate, move, and slide past each other.

Gas

Particles are very separated, vibrating and moving quickly.

Condensation

The process where gas turns into liquid, such as dew on grass.

Evaporation

The process where liquid turns into gas, as seen when puddles disappear.

Freezing Point

The temperature at which a liquid turns into a solid, e.g., water to ice.

Sublimation

A change of state from solid to gas without passing through the liquid state.

Deposition

A change of state from gas to solid, the reverse of sublimation.

Matter

Anything that has volume (takes up space) and has mass.

Mass

The amount of matter in an object, often measured by weight.

Volume

The three-dimensional (3D) space an object takes up.

Density

Mass of an object compared to its volume; calculated as mass divided by volume.

Graduated Cylinder

An instrument used to measure the volume of an object by water displacement.

Physical Property

A characteristic that can be observed or measured without changing the substance.

Chemical Property

A characteristic observed when matter changes into a new or different substance.
