Amber noticed that when she breathed on a cold mirror, the glass fogged up. Which of the following best explains why this happened?

• Amber’s breath caused a physical change, which froze the mirror.

• Cooling caused a physical change, which caused Amber’s breath to condense on the mirror.

• Amber’s breath cooled the mirror and caused a chemical change, which produced a white substance.

• Cooling caused a chemical change, which turned oxygen from Amber’s breath to water on the mirror.
