Lily bought a dozen inflated balloons for her birthday party. When she got home, she left the balloons outside in the hot sun. After a while, two of the balloons popped. She brought the rest of the balloons into her air-conditioned home.
Lily then decided to try an investigation. She put one of the balloons in the freezer for an hour. When she took it out, she observed that the balloon had shriveled.
Using thermal energy transfer and collisions as evidence, what happened to Lily's balloons in the sun?
* As the thermal energy of the particles inside the balloon increases, the particles moved faster and collided more with the sides of some of the balloons. This caused some of the balloons to pop.
* Thermal energy caused the ballons to expand
