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?
Answer
A
The air from the outside comes inside the balloon. More air means more volume.
B
The air warms and increases particle movement. Increased particle movement leads to increased volume.
C
Increased temperature means increased volume as long as the container is flexible.
