Answer:
Condensation.
Explanation:
The boiling point of water is much higher than that of either nitrogen or oxygen gas . So when the mixture is condensed to a temperature lower than
100°C , water vapor will come out first in the form of water leaving other
elements of mixture in gaseous phase. In this way, water vapor will get separated from others.
The galaxies aren't distributed randomly throughout the universe but they are grouped in gravitationally bound clusters.
Ocean waves propagate through the medium called 'sea water'.
