Water is heavier than air, but that doesn't stop the rain, does it?

Water is heavier than air, but that doesn't stop the rain, does it?
- kijin 8y agoThat's not a good counterexample because rain comes down. Water vapor, which goes up, is actually lighter than air by a large margin (0.804g/L versus 1.225g/L) at the same temperature and pressure.
- SmellyGeekBoy 8y agoWater vapour is water.
- Retra 8y agoLiquid water is certainly denser than air, and the fact that it vaporizes before rising up into the atmosphere is immaterial to the point that it ends up there anyway. The process (evaporation and subsequent fluid mixing) is not significantly different from the process which puts ozone in the upper atmosphere.
