The answer is weak intermolecular attractions volume and shape of container. The molecules of gases have high kinetic energy compared to those of liquids and solids hence they are farther apart from one another. This results to weak intermolecular forces. Gases also expand to fit the container hence have no definite shape or volume.
a because it was a combination of lots of subtances like CO2, oxygen, nitrogen,... and u cant see air so it is a homogenous mixture
