Understanding Matter

Front

Definition of Matter

Back

Matter is anything that has mass and volume. Examples include objects like a ball, liquids like water, and gases like air.

States of Matter: Solids

Back

Solids have a definite shape and volume; particles are tightly packed and only vibrate in place.

Front

States of Matter: Liquids

Back

Liquids have a definite volume but take the shape of their container; particles move around each other.

Front

States of Matter: Gases

Back

Gases have no definite shape or volume; particles move freely and can expand to fill any container.

Mass vs. Weight

Back

Mass is the intrinsic property representing the amount of matter in an object. Weight is the force exerted on mass by gravity.

Particle Theory of Matter

Back

Matter is composed of particles that are always in motion and are attracted to each other. Their movement differs by state.

Front

Effect of Temperature on Particles

Back

The kinetic energy of particles increases with temperature, causing them to move faster and spread out.

Observable Phenomena Explained by Particle Theory

Back

When you heat a liquid, it can evaporate into a gas as particles gain enough energy to break free.

Front

Diffusion

Back

Particles spreading out from a concentrated area, like the smell of popcorn spreading in a room.

Observable Properties

Back

Properties of solids, liquids, and gases due to different movements and attractions between particles.
