Revolt · Accepted Answer

✔ 11.2 L

Question 2

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?

Revolt · Accepted Answer

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.
