Q: What results when the water vapor from a hot shower contacts the cooler surface of a mirror?


Read this paragraph and choose the correct option from the provided answers:

If you take a hot shower in a closed bathroom, the mirror is likely to "fog" up. The "fog" consists of tiny droplets of water that form on the cool surface of the mirror. Why does this happen? Some of the hot water from the shower evaporates, so the air in the bathroom contains a lot of water vapor. When the water vapor contacts cooler surfaces, such as the mirror, it cools and loses energy. The cooler water particles no longer have enough energy to overcome the forces of attraction between them. They come together and form droplets of liquid water.

 Choices:

- the mirror breaks

- mirror brightens

- cleaner mirror

- foggy mirror


A:
foggy mirror
