“ In its modern form,the first law of thermodynamics has its empirical basis in a series of experiments conducted by Joule between 1843 and 1848.He used a system surrounded by adiabatic walls,which do not allow the system to be affected by temperature differences between the system and the surroundings.He did work on such an adiabatic system in a variety of ways,using the rotation of a paddle wheel,the passge of an electric current, friction, and the compression of a gas. He concluded that system. Thus, to produce a given change of state, the adiabatic work required is independent of the path by which the change is achieved.
Therefore, it seems appropriate to define a quantity, the energy
