Are clouds a solid, liquid, or gas?
I have been looking online and they are often described ambiguously as a "mass". For instance, from NASA:
A cloud is a mass of water drops or ice crystals suspended in the atmosphere. Clouds form when water condenses in the sky. The condensation lets us see the water vapor. There are many different types of clouds. Clouds are an important part of Earth’s weather and climate.
Since they describe it as a vapor, that makes me think it is indeed a gas. But condensation is by definition the change of state from a gas to a liquid. So that makes it sound like it could be a liquid, or contain liquid droplets rather than "freely moving" molecules that typically make up a gas.
But at another web site, which doesn't seem all that authoritative, it says that clouds are a solid, liquid, and gas simultaneously!
A cloud is a liquid, a solid, and a gas.
That does seem intriguing. If I remember correctly, liquids are supposed to be incompressible, and clouds are likely compressible.
