what is the definition of the Gas?

Sagot :

gas does not have definite shape or volume.it take shape of their containers. the atoms in a gas are spread out and move freely.
Gas is one of the five phases of matter which are solid, liquid, gas, plasma, and Bose Einstein condensates. Its atoms are very far from each other, that's why we cannot see them, unlike solid whose atoms are compressed and very close to each other.
