As a chemistry rule, all air-air mixtures are homogeneous. So the air is a mixture of Nitrogen, Oxygen, Co2 and some more gases, the air is homogeneous.
No air is not a homogeneous mixture, air is a heterogeneous mixture.
When an air mass forms near the poles it has warm air. This will be a large body of air which will have homogeneous moisture.
It depends on the kind of area you are talking about... but for a test I'd say Homogeneous meaning it is the same throughout. Sorry, more to the point, eventually air will come to be homogeneous unless you have something that is not mixing like a level of smog or a rain cloud. *For a test I'd still say Homogeneous, but it is a terrible question. Usually teachers tell you in their lectures or it is in your book, the answer that they want.
They can be either one. For instance, ozone is a gas and is there homogeneous, but soot particles are suspended solids (aerosols) and are therefore heterogeneous.
Yes. It is a homogeneous mixture. It is a heterogeneous mixture. COLLOID because it does not settle but at the same time it makes stuff Smokey for example if you put a cup of water in a sun ray you may see little wavy things almost like hair flying in to the water and it sort of makes if foggy Dusty air is a suspension. The dust particles keep their shape. There is nothing in air to dissolve dust. mixture
