Phase Change Graphs Practice

Front

What is a phase change?

Back

A phase change is a transition of matter from one state (solid, liquid, gas) to another due to the addition or removal of heat.

Front

What happens during freezing?

Back

During freezing, a liquid loses heat and changes into a solid as the particles slow down and come closer together.

Front

What is a cooling curve?

Back

A cooling curve is a graph that shows the temperature of a substance as it cools and undergoes phase changes.

Front

What occurs during melting?

Back

During melting, a solid gains heat and changes into a liquid as the particles gain energy and move apart.

Front

What is condensation?

Back

Condensation is the process where a gas loses heat and changes into a liquid, causing the particles to come closer together.

Front

What is boiling?

Back

Boiling is the rapid vaporization of a liquid when it reaches its boiling point, where particles gain enough energy to escape into the gas phase.

Front

What is the boiling point?

Back

The boiling point is the temperature at which a liquid turns into a gas.

Front

What is the melting point?

Back

The melting point is the temperature at which a solid turns into a liquid.

Front

How do particles behave during a phase change?

Back

During a phase change, the arrangement and energy of particles change, affecting their distance and movement.

Front

What happens to the temperature during a phase change?

Back

During a phase change, the temperature remains constant while the substance changes state.
