*&^%##!&^$ Nanyang paper.

And I want to know, at least in theory, how evaporation always takes place at any temperature, unless that is not what we are taught, in which case pray tell me what we are actually supposed to learn. I understand the bit about when the more energetic molecules leave the surface of the liquid, kinetic energy level drops, therefore temperature drops, and energy from surroundings which are now at higher temperature than the liquid go into liquid and more evaporation can take place because there will now be molecules with enough energy to go further apart from everybody and become a gas. What if (in theory) surrounding temperature drops together with temperature of liquid when initial evaporation takes place, so that there is no flow of energy from surroundings to liquid, and therefore there are no more molecules with enough energy to leave the surface of the liquid? Will evaporation stop?

*^%$@&%$#& evaporation.
