Question

I'll medal for help!!
Materials needed:

Large hand mirror
Teakettle
Glove, potholder, or tongs
Procedure:

Put the mirror in the freezer for several minutes, until it is very cold.
Bring water to a boil in the teakettle.
Steam from boiling water can burn your hands! Using glove, potholder, or tongs, hold the mirror above the steam rising from the kettle.
Answer the following question in your journal.
Describe what happened in the experiment, using the terms condensation, evaporation, precipitation, rain, and phase change. I have this assignment, but I only have a really big mirror.

Answer 1

When steam come out from the teakettle, that is evaporation
2. Condensation occurs when water vapor from the teakettle cools when touch the cold mirror (you can see the water droplets in the mirror surface). Cooling of water vapor is called condensation
3. Precipitation happens when the air cannot anymore hold the cold water vapor in the attached to the mirror and falls down. This phenomenon is similar to rain - when the cold vapor in the air is bigger and heavier that the air cannot hold anymore, then it will fall as rain.

So, phase change occur during evaporation (liquid to gas) and condensation (gas to liquid) in this experiment.
