Why is the Kelvin scale formed using the triple point of water rather than the freezing point?
Because the triple point of water is NOT set for 1 atmosphere of pressure:
Note how its a diagram of pressure against temperature, and whilst not to scale at all, it does paint a picture.

Collecting condensed air
In order to dissipate the most heat in the fastest manner, you would need a long, narrow tube. It should be narrow because objects with a high surface are to volume ratio lose more heat, but you want …

Why does the temperature of an object rise to a certain level and stop under sunlight?
It's all to do with the laws of thermal dynamics, in particular with how an object emits radiation with temperature: see the Stefan-Boltzmann law
You can see with metals, that once you heat them up t …

How can I boil water at a temperature less than 100 degree Celcius?
lower the air pressure, at the top of mount everest you can boil water at about 71 celcius, but this will of course be hard to replicate at normal atmospheric pressure
" For comparison, on top of Mou …
