Question

Gases have neither definite volume nor definite shape. Why?

Answer 1

Gases do not have a definite shape or volume because of the following reasons:

• Gases try to fill to the whole of the closed container and no definite volume it depends on the container.
• The molecules in gases are very loosely packed, they have large intermolecular spaces and hence they move freely without any restriction.
• The kinetic energies between the molecules is high enough to break away from any boundaries and they move randomly.
• Gases have very less force of attraction, as a result gases acquire any shape or any volume.
