Phase Change Graphs # 2

Front

What is a phase change graph?

Back

A phase change graph visually represents the changes in state of a substance as it is heated or cooled, showing the relationship between temperature and time.

What happens to the energy of a substance during a phase change?

Back

During a phase change, the energy of a substance is either gained or lost, depending on whether it is melting, freezing, vaporizing, or condensing.

Back

Freezing.

Front

What is sublimation?

Back

Sublimation is the process where a solid turns directly into a gas without passing through the liquid state.

Front

What happens to the particles of a substance during melting?

Back

During melting, the particles gain energy and move apart, transitioning from a solid to a liquid.

Front

What happens to the particles of a substance during freezing?

Back

During freezing, the particles lose energy and come closer together, transitioning from a liquid to a solid.

Front

What happens to the particles of a substance during vaporization?

Back

During vaporization, the particles gain energy and move further apart, transitioning from a liquid to a gas.
