In physics, thermodynamics is the study of energy conversion between heat and mechanical work, and subsequently the macroscopic variables such as temperature, volume and pressure. For example, if the system is one mole of a gas in a container, then the boundary is simply the inner wall of the container itself. Go forward on a (gaining Ua) and backward along b, During each cycle there is a net gain in energy, We could repeat this and gain energy from doing, Not possible, therefore, DUa DUb.

The Third Law of Thermodynamics means that as the temperature of a system approaches absolute zero, its entropy approaches a constant (for pure perfect crystals, this constant is zero). According to the third law, the reason that T=0 cannot be reached is explained as follows: Suppose the temperature of a substance can be reduced in an isentropic process by changing the parameter X from X2 to X1. It provides the basis for the calculation of absolute entropies of the substances. Now customize the name of a clipboard to store your clips. I.e.
