Front

What occurs during melting?

Back

Melting is the phase change from a solid to a liquid.

Front

What is the relationship between temperature and phase changes?

Back

Temperature changes can cause substances to gain or lose energy, leading to phase changes.

Front

What is the significance of energy in phase changes?

Back

Energy determines whether a substance will change from one phase to another, either absorbing or releasing energy.

Front

What is an example of a substance undergoing vaporization?

Back

Water boiling to form steam is an example of vaporization.

Front

What is an example of sublimation?

Back

Dry ice (solid carbon dioxide) turning directly into gas is an example of sublimation.
