1. What are the characteristics of a gas?

Answer 1

Answer:

$\boxed {\boxed {\sf \ Choice \ B }}$

Explanation:

Gas particles possess a great amount of kinetic energy, and they move around rapidly to fill the container they are in. They are also unique for their high compressibility and the fact they occupy a lot of space.

Gas doesn't have a definite shape of volume. So, B (no definite shape or volume) is the correct answer.
