Temperature.

Front

In which regions of a heating curve does the temperature increase?

Back

Regions A, C, and E.

Front

What does point A represent in a particle diagram on a heating curve?

Back

(Particle diagram representation needed).

Front

What is a heating curve?

Back

A graph that shows the temperature change of a substance as it is heated over time.

Front

What happens during the melting phase on a heating curve?

Back

Solid turns into liquid as heat is added.

Front

What occurs during the freezing phase on a heating curve?

Back

Liquid turns into solid as heat is removed.

Front

What is the significance of the plateau regions on a heating curve?

Back

They indicate phase changes where temperature remains constant.

Front

What is vaporization in the context of a heating curve?

Back

The process where a liquid turns into a gas.
