States of Matter and Properties

These flashcards cover key concepts related to states of matter, properties, and measurements.

Solid

A state of matter where particles are tightly packed and do not move around.

Liquid

A state of matter where particles are close together but can vibrate, move, and slide past each other.

Gas

A state of matter where particles are very separated and move quickly.

Condensation

The process of gas turning into liquid, e.g., dew on grass.

Evaporation

The process of liquid turning into gas, e.g., puddles disappearing.

Freezing Point

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

Sublimation

The change of state from solid to gas without passing through a liquid state.

Deposition

The change of state from gas to solid.

Matter

Anything that has volume and has mass.

Mass

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

Volume

The three-dimensional space an object occupies.

Density

The 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 the amount of water it displaces.

Physical Property

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

Chemical Property

A characteristic that can be observed when the matter changes into a new or different substance.

Scale

An instrument used to weigh an object.
