You think probable to bubbling.
When a liquid spreads throughout a gas, it is called evaporation. This occurs when the liquid molecules gain enough kinetic energy to escape into the gas phase. The liquid molecules disperse into the surrounding gas until an equilibrium is reached.
One liquid spread throughout another liquid would be an emulsion. The two liquids do not interact.
Gas certainty and liquid if the container is absolutely full.
The molecules in a gas are spread further apart than those in a liquid.
Gas, because it has evaporated (turned from liquid to gas). Although, in a cloud it's not really a gas but lots of little drops of liquid water that have been spread out.
a suspension
A liquid with bubbles. :)
diffusion
perhaps a Foam?
