Why neither liquids nor gases have fixed shapes?

Answer 1

Gases don't have a definite shape because the molecules aren't tightly packed together like solids and liquid's molecules are. The molecules in the gas are spread out and move freely about quickly in all directions.

Answer 2

because the atoms are so far apart from each other.

Answer 3

Both liquids and gasses have molecules that are spread apart, and thus can shift shapes and mold to different positions.

Answer 4

Gases and liquids tend to spread out or across whatever substance is confining them because their molecules are in motion

Answer 5

the atoms are loosely bonded in liquids or gases and hence they can move about easily and take the shape of the container they occupy
