My chemistry teacher recently made something that must be one of the most stupid statements ever made:
She claimed that this was a demonstration of the 2nd law of thermodynamics
"We can usethe analogy of dissolving sugar in coffee as an example of increasing entropy, in this case - disorder. No matter how you stirred, the sugar would not separate from the coffee again because that would be bringing order out of chaos."
Isn't that ridiculous? Crystallisation is an exothermic reaction and could anyone be so dumb as to think that an exothermic reaction could proceed when you add mechanical energy to it.
It just shows hercomplete lack of understanding of thermodynamics in her insistence of using a false 'analogy' involving the spontaneity of an exothermic process depending on the addition of mechanical energy.
But she refuses to admit she was wrong!
