Evapouration is OU

[buzneg]

Or more technically energy from heat, and heat which is particle vibrational energy. When evapouration happens like sweeting, the animal is cooled down because the colder particles of the water are left behind as the hotter ones evapourate into the air. This is a natural heat difference, the physical separation of the nano scale heat differences, from particle to particle. Look at this Brownian Motion simulation, since heat is the speed at which the particles move, you can see that some particle seem to be near absolute zero, whereas others are probably thousands of degree's. I don't think threre's a way to build a practical device to capture this energy though.

Of course, the heat originates from elsewhere. Energy is imparted from an external source which, itself, gained energy from various external sources.

Along the same lines, on the molecular level, a container of gas has both high and low-energy molecules, which translates to a range of higher and lower temperatures (Ideal gas law).

You may already be familiar with this device, which can seperate these molecules:

Keep in mind that the energy imparted to the container of gas is a result of both the ambient entering-temperature and (mainly) the compression of the gas in the container, so the energy is externally derived, in any case.

Again, this is at the 'macro' or molecular level, the atomic and sub-atomic are another matter.
