What Is a Gas?
A gas is a special kind of matter that we usually can't see with our eyes! Imagine blowing up a balloon; the air inside is a gas! Gases are unique because they spread out to fill all the space around them. For instance, when you open a jar of delicious cookies, the yummy smell travels through the air. You can smell those cookies even if you're far away! That's because tiny gas particles, which are like little invisible messengers, carry the cookie smell through the air and into your nose. Isn't it amazing how gases can move around and help us smell things? Gases are all around us, even if we can't see them, and they play a big role in our everyday lives!
