But why on Earth does it have to be so cold up there? We all know that the higher you go, the colder it gets, but why? Altitude affects the temperature of the air because air pressure gets lower as the altitude increases.

The gravitational attraction(*) between the earth and air molecules is greater for those molecules nearer to earth than those further away - they have more weight - dragging them closer together and increasing the pressure (force per unit area) between them. Molecules further away from the earth have less weight (because gravitational attraction is less) but they are also 'standing' on the molecules below them, causing compression

The work done in compressing the gas is recovered as the piston moves back down the cylinder under the pressure of the compressed gas (less friction losses etc.) If the piston compresses the gas to half its original volume, then it has a compression ratio of 2:1, as the piston recovers it can do work based on the compression it started with.

Vapor pressure increases with increasing temperature, so when there is less atmospheric pressure, a smaller vapor pressure is required to get the water boiling, hence a lower boiling temperature.
