Lecture 4: 09.16.05 Temperature, heat, and entropy
... •� Work and heat are not state functions; they are path dependent- what does this mean? In most physical situations, we are concerned with a quantity of heat or work transferred into or out of a material, which causes a change from one state of the material to another. Path dependence implies that t ...
