What are the four states of matter?

Back

The four states of matter are solid, liquid, gas, and plasma.

Front

How does plasma differ from gas?

Back

Plasma is a gas that has been energized to the point that some of its electrons are no longer associated with a specific atom, resulting in charged particles.

Front

What is an example of plasma?

Back

Examples of plasma include the sun, lightning, and neon signs.

Front

What happens to gas when it is heated to extremely high temperatures?

Back

When gas is heated to extremely high temperatures, it can become plasma.

Front

What is condensation?

Back

Condensation is the process by which water vapor in the air cools and changes into liquid water, forming droplets.

Front

What is the process of melting?

Back

Melting is the phase change from solid to liquid that occurs when a solid is heated.

Front

What is the process of boiling?

Back

Boiling is the phase change from liquid to gas that occurs when a liquid is heated to its boiling point.

Front

What is the role of temperature in phase changes?

Back

Temperature affects the energy of particles, which can lead to phase changes such as melting, freezing, boiling, and condensing.

Front

What is the definition of a solid?

Back

A solid is a state of matter characterized by closely packed molecules that have a fixed shape and volume.
