Question

A student blows up a balloon and then places it in a very cold freezer. After a few hours, the balloon has shrunk. Which of the following best explains why the balloon shrunk.

As the balloon gets cooler, the molecules gain energy and move closer together, causing the balloon to shrink.
As the balloon gets cooler, the molecules lose energy and move closer together causing the balloon to shrink.
As the balloon gets cooler, the molecules break apart, decreasing the volume of the gas.
As the balloon absorbs energy, the molecules move more quickly, making the balloon expand.

Answer 1

Well, which options can you eliminate? If the statement tells you that the balloon shrink, you can clearly eliminate one choice.

Answer 2

D

Answer 3

Yes, so now you're left with A, B, or C. Now, if you're decreasing temperature (remember that energy is related to molecule movement) what else does that mean? They start taking on a smaller volume, and move less.

Answer 4

So B

Answer 5
