Answer 1

Fog is best described as a colloid.

In the atmosphere, fog is described as a thick cloud of tiny water droplets suspended to an extent that it restricts visibility to human eyes and also causes irritation.

Defining a colloid- we can say it is a mixture (heterogenous mixture) in which the particles that are dispersed have size that is intermediate between particles of solution and suspensions.

Like a colloid, Fog particles do not settle on standing and nor can it be separated by filtration process.

So fog is a COLLOID.
