Do Gases Have a Definite Volume?

A gas has neither a definite shape nor a definite volume. Like liquids, gases are fluids. The particles in a gas can move around one another freely. If a gas is released in a closed container, the gas particles will move in all directions and spread apart as they fill the container.

Why gas has no definite volume?

Gases do not have a definite shape or volume because the molecules in gases are very loosely packed, they have large intermolecular spaces and hence they move around. ... The particles of solid are closely packed and occupy less space while particles of gases are loosely packed and occupy the complete space available.

Do gases have definite volume and mass?

Solids are the ones who have rigid structure and which have a definite volume and shape. ... - Therefore, gases take the shape of the container and occupy the complete volume of that particular container. - Thus, the correct answer to this question is that gases have definite mass but no definite volume and shape.
