"Where do water droplets come from" PPT courseware on changes in temperature and water

Knowledge explanation

I took out a popsicle from the freezer. After a while, I found a layer of white frost on the popsicle paper. When I peeled off the paper, "white smoke" came out around the popsicle.

Put the popsicle in the cup. After a while, the ice melted and the outer wall of the cup "sweated", and droplets of water appeared.

Thinking: Where do water drops come from?

Think about it and guess:

Where do the small water droplets on the outer wall of the ice glass come from?

Probably seeping out of the cup.

The ice melts into water and overflows from the mouth of the cup.

It may be that when adding ice, the ice cubes hit the rim of the glass and turned into water and flowed down.

We concluded that the small water droplets on the outer wall of the glass were not formed by the melting of ice inside the glass.

Is the formation of small water droplets on the outer wall of the glass related to ice? Why?

The water droplets on the outer wall of the glass are:

When the water vapor in the air encounters the cold wall of the glass, the water vapor cools rapidly and condenses into a liquid.

Condensation: The process of changing from gas to liquid is called condensation.
