WebMay 20, 2024 · The first law of thermodynamics is a restatement of the general principle known as the law of the conservation of energy. The second law of thermodynamics describes the kinds of thermodynamic processes that cannot occur in nature and explains why this is the case. According to the first rule of thermodynamics, sometimes referred … WebΔ Q = Δ U + W. Where, ΔQ is the heat given or lost. ΔU is the change in internal energy. W is the work done. We can also represent the above equation as follows, Δ U = Δ Q − W. So we can infer from the above equation that the quantity (ΔQ – W) is independent of the path taken to change the state.
WebMay 1, 2024 · Thermodynamics is a funny subject. The first time you go through it, you don't understand it at all. The second time you go through it, you think you understand it, except for one or two small points. The third time you go through it, you know you don't understand it, but by that time you are so used to it, it doesn't bother you any more.
