A scientist takes a small, partially inflated balloon
out of liquid nitrogen (at a very low temperature).
As the balloon rests on the table, it begins to grow
in size. Which statement(s) best explains why the
balloon grows?

The air from the outside comes inside the
balloon. More air means more volume.
The air warms and increases particle
movement. Increased particle movement
leads to increased volume.

Increased temperature means increased
volume as long as the container is flexible.

According to coulomb's law, how would the electrical force between particles change if the product of their electrical charge increased?
