What happens to the particles in a solid?

Back

They are closely packed together and vibrate in place.

Front

What happens to the particles in a liquid?

Back

They are close together but can move past each other, allowing liquids to flow.

Front

What happens to the particles in a gas?

Back

They are far apart and move freely, filling the space available.

Front

What is a phase change?

Back

A transition of matter from one state to another, such as melting or freezing.

Front

What is thermal energy?

Back

The energy that comes from the temperature of matter; it is the total kinetic energy of particles.

Front

What occurs during melting?

Back

A solid absorbs thermal energy and changes into a liquid.

Front

What occurs during freezing?

Back

A liquid loses thermal energy and changes into a solid.

Front

What is condensation?

Back

The process where a gas loses thermal energy and changes into a liquid.

Front

What is evaporation?

Back

The process where a liquid gains thermal energy and changes into a gas.
