It continues to cool until it reaches it's boilng point. At which it will condense then cool further until it reaches it's melting point. It will then continue to cool until it's entropy is minized at absolute zero.
As we reduce the temperature initially the density of water increases. It reaches to the maximum value at 4 deg celcius. And when the temperature is further reduced then its density decreases due to expansion. This is what we call ANOMALOUS expansion. At 0 degree water freezes and density decreases
The air or gas mixture can be cooled down to a very low temperature until it liquefies. It is then allowed to heat up slowly, as the liquid air reaches different temperatures, the boiling points for each gas, the gas is extracted.
When any gas (or gas mixture), including air, is cooled, the molecules will move slower and they will be able to be closer together. The volume needed to store a certain amount of gas will be less. If you cool it enough, it will eventually turn into a liquid.
Water is most dense at +4 deg centigrade. When it freezes it becomes lighter.
As water is cooled its density increases until it reaches about 4 C and then it decreases.

Water in a lake is usually cooled by the cold air above its surface rather than from the ground underneath it. As the top layer of water cools its density increases and so it sinks to the bottom, bringing other water up to the surface. This water is then cooled. This carries on until the temperature reaches 4 deg C when the density reaches a maximum. Further cooling lowers the temperature of the top layer but now its density is less than that of the water below so the top layer stays on top until it freezes (if it is cold enough). That is how you can get lakes with a frozen surface but liquid water below which can sustain aquatic life and also destroy human or other life forms that fall through the ice!
Density increases until 4 degrees of celcius.Then decrease again.
Buoyant air will rise until it reaches warmer air that is the same density as itself.
As θ increases from 0 to π/2 (90o) sin θ increases until it reaches a maximum value of 1 when θ = π/2. As θ increases from π/2 (90o) to 3π/2 (270o) sin θ decreases until it reaches a minimum value of -1 when θ = 3π/2. As θ increases from 3π/2 (270o) to 3π (360o) sin θ increases until it reaches the value of 0 it had when θ = 0. From this point, as θ increases (by the same amounts) sin θ repeats this same cyclic behaviour.
It continues to cool until it reaches it's boilng point. At which it will condense then cool further until it reaches it's melting point. It will then continue to cool until it's entropy is minized at absolute zero.
When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%
Actually, as you go from the surface of the earth to space, temperature decreases until it reaches approximately 15 km( the tropopause). Then it increases until it reaches approximately 50 km ( stratosphere) . then it decreases again until the dheight is about 80 km ( mesosphere), then it increases again in the thermosphere up until 120 km above sea level.
It melts if has frozen, but far more interestingly, the volume of the water contracts until the temperature reaches 4 degrees C. That is the point of maximum density of water. Once past 4 C, the volume increases slowly (as the density declines) with more added heat.
It increases - until within 4 degrees of freezing, where it decreases.
