Second law of thermodynamics - Wikipedia
https://en.m.wikipedia.org/wiki/Second_law_of_thermodynamics
WebThe second law of thermodynamics is a physical law based on universal empirical observation concerning heat and energy interconversions. A simple statement of the law is that heat always flows spontaneously from hotter to colder regions of matter (or 'downhill' in terms of the temperature gradient).
