Question

Part IYou blow up a balloon with your own breath and then put it in a freezer. Tell me about what happens to the size of it. Make sure to use the KMT (kinetic molecular theory) to support your answer. Part IITake the same balloon we filled up with our breath. Tell me what would happen if we put it outside and let it sit in the sun for a bit. Again, support your answer using the KMT.In both part I and part II we are going to be under the impression that no air can escape from the balloon.View keyboard shortcuts

Answer 1

Step-by-step explanation

When a balloon is blown up with the human breath, the balloon will increase in its size because there is air inside the balloon. When put in a freezer the size of the balloon will shrink, and this would reduce the size of the balloon.

Recall that, the balloon contains air, and when put in the freezer the temperature will reduce.

According to kinetic molecular theory (KMT), the average kinetic energy is a function of the temperature.

So, when the balloon is put inside the freezer, the temperature of the gas will decrease thereby decreasing the average kinetic energy. This happens because the gas molecules move more slowly and there are fewer collisions of the gas molecules with the inside wall of the balloon
