A teacher took two latex balloons and blew them up with helium gas to the same size. She took one and labeled it Balloon A and placed it in a -15o C freezer. The second one she labeled BALLOON B, and she took it outside and tied it to the railing in the sun on a 30o C day. After a half hour, she had the students measure the circumference of each balloon. Which TWO outcomes do you predict the students will find and why?

Balloon A will have increased in size because the molecules will gain energy and move further apart.

Balloon B will have increased in size because the molecules will gain energy and move further apart.

Balloon B will have decreased in size because the molecules will lose energy and move closer together.

Balloon A will have decreased in size because the molecules will lose energy and move closer together.

Both balloons will be the same size because they will reach the same temperature as their environment and will be in thermal equilibrium with no molecules moving.
