Thanks, good points! I meant solid ice, wrote it like that because I wanted to emphasize their states of matter for clarity thinking students might find the emphasis useful, but you’re correct, that is technically redundant. Mist and snow are examples of airborne forms of water that are not in the gaseous state. Perhaps gases trapped in containers or floating in outer space could be considered not airborne if there is no air (nitrogen, oxygen, argon, carbon dioxide, …) to mix it with?
