    Water vapour isn’t really applicable here, unless you’re talking about very low pressures. Although you could consider it a component in a mixed gas, it’s not really gaseous water. The true gaseous form of water is steam. Water vapour is more like water that has been dissolved in the atmosphere.

    By analogy: sugar is solid at room temperature. But you can dissolve it in water. Have you converted the sugar into a liquid? No. Because sugar is a liquid only at temperatures above 160°C. But the resulting mixture is liquid.

      Agreed that vapour doesn’t really play in to this, but I knew if I didn’t mention it someone would come in and ‘correct’ me. So I included it, and someone still came in and ‘corrected’ me.

      My main point, that I didn’t make very well, is that I wanted to ‘correct’ the meme that both ice and liquid water can be at 0°C.

      Technically correct is the best kind of correct.
