Question

Give reason:- A gas can fill the whole vessel in which it is enclosed.

Answer 1

Hey dear !!
So here is your answer:-


As gas neither has a fixed shape nor a fixed volume.
As the particles of the gas are free to move anywhere, it assumes the shape and volume of the vessel in which it is enclosed.✔

Hope this helps you dear ✌
