Physical Science
The study of heat and its relation to fluid properties, and the performance of work upon and by fluids, is called thermodynamics. The subject can be taught using two or three laws of thermodynamics, without dealing with kinetic theory. The kinetic theory of matter can be used ...

The 2nd law of thermodynamics states that “in any spontaneous process, the total entropy of the universe always increases”. Yet in biological systems there are processes where there is a decrease in entropy during a reaction. Give an example of a biological process where ...
