Question

on the basis of molecular theory,explain why a gas has niether definite shape nor definite volume

Answer 1

Explanation:

The molecules in a gas are very far apart compared with the molecules in a solid or a liquid. The amount of space between the molecules in a gas can change easily. If a rigid container—one that cannot change its shape—has a certain amount of air and more air is pumped in, the volume of the gas does not change.(◍•ᴗ•◍)

Answer 2

Particles are far apart from each other because there are very weak forces of attraction between them. They move fast in all directions. Because of this, gases don't have a definite shape or volume and fill any container. Because there is lots of free space between particles, gases can easily be compressed.
