Examples of laws of thermodynamics
WebFor example, in the case of a melting block of ice, a highly structured and orderly system of water molecules changes into a disorderly liquid, in which molecules have no fixed positions ( Figure 12.11 ). There is a large increase in entropy for this process, as we'll see in the following worked example. WebThere are four laws of thermodynamics: The zeroth law: the law of thermal equilibrium. The first law: the law that describes the internal energy of a substance. The second law: the entropy law of irreversibility. The third law: the law that states that at zero kelvin, entropy reaches a constant value.
