States of Matter

Front

What is a solid?

Back

A state of matter where particles are packed tightly together, held by strong attractive forces, and vibrate in fixed positions.

Front

What happens during freezing?

Back

When heat is removed, a liquid changes into a solid, such as water turning into ice.

Front

What is a gas?

Back

A state of matter where particles move rapidly in all directions, are at great distances from one another, and have less effect from attractive forces.

Front

What are examples of gases?

Back

Oxygen, carbon dioxide, helium, steam (water vapor), ozone, hydrogen, and air.

Front

What is deposition?

Back

The process where gas changes directly into a solid, skipping the liquid phase, such as water vapor changing into frost.

Front

What is a liquid?

Back

A state of matter where particles are close together but can move past one another, allowing liquids to flow.

Front

What happens during evaporation?

Back

The process where a liquid changes into a gas when heat is added.

Front

What is condensation?

Back

The process where a gas changes into a liquid when heat is removed.

Front

What is plasma?

Back

A state of matter where gas particles are energized to the point that they become charged, consisting of ions and free electrons.

Front

What is the difference between a solid and a liquid?

Back

In solids, particles are fixed in place, while in liquids, particles can move past each other.
