Second law of thermodynamics
The second law of thermodynamics is a physical law based on universal experience concerning heat and energy interconversions. A simple statement of the law is that heat always flows spontaneously from hotter to colder regions of matter. Another statement is: "Not all heat can be converted into work in a cyclic process."
