thermodynamics. The principles of thermodynamics have been enunciated in the form of a few laws of thermodynamics called zeroth law, first law, second law and third law. These laws find applications in physics, chemistry, engineering, medicine, biotechnology, biochemistry, geology and space sciences. The branch of chemistry dealing with the Although thermodynamics tells us nothing whatsoever of the microscopic explanation of macroscopic changes, it is useful because it can be used to quantify many unknowns. Thermodynamics is useful precisely because some quantities are easier to measure than others. The laws of thermodynamics provide an elegant mathematical expression of some
