2.2 States of Matter

Front

What are the four main states of matter?

Back

Solid, Liquid, Gas, Plasma.

Front

What is a solid?

Back

A state of matter with a definite shape and volume, where particles are closely packed together and vibrate in place.

Front

What is a liquid?

Back

A state of matter that has a definite volume but takes the shape of its container, with particles that are close together but can move past one another.

Front

What is a gas?

Back

A state of matter that has no definite shape or volume, with particles that are far apart and move freely.

Front

What is plasma?

Back

A state of matter similar to gas but with charged particles, created at extremely high temperatures.

Front

How do particles behave in a solid?

Back

Particles in a solid vibrate in place and are tightly packed, giving it a fixed shape.

Front

How do particles behave in a liquid?

Back

Particles in a liquid are close together but can slide past one another, allowing liquids to flow.

Front

How do particles behave in a gas?

Back

Particles in a gas are far apart and move freely, filling the entire volume of their container.

Front

What happens to particles when a substance is heated?

Back

Particles gain energy, move faster, and may change state (e.g., solid to liquid, liquid to gas).

Front

What happens to particles when a substance is cooled?

Back

Particles lose energy, move slower, and may change state (e.g., gas to liquid, liquid to solid).
