Question

1. A dry, empty bottle is placed in an ice bath. After the air inside the bottle is cooled off, a balloon is placed

over the opening. The bottle with the balloon is then placed in very hot water and the balloon inflated. Why
did the balloon inflate?

Answer 1

hot air rises and expanded the balloon

Step-by-step explanation:

thats it.

Answer 2

The hot air rises and expanded the ballon. This is as the air in the bottle cools down, the molecules of the air slow down and take up less space because they move closer together. The air then moves out of the balloon and back into the bottle, causing the balloon to deflate.
