C. The dissolution of salt in water is a spontaneous process in which the entropy of the system increases.
The entropy of a system is a measure of its disorder. In a spontaneous process, the entropy of a system increases. This is because in a spontaneous process, energy is exchanged between the system and its environment and the entropy of the environment always increases. An example of this is the dissolution of salt in water. Salt is composed of ions, which are charged particles. When salt is placed in water, the ions are attracted to the polar molecules of the water and the salt dissolves. This process is spontaneous because the entropy of the system increases. The entropy increases because the ions become more evenly distributed in the water, creating a higher degree of disorder. The energy released in this process is the result of the attraction between the ions and the water molecules, which lowers the overall energy of the system. This energy is then released as heat, further increasing the entropy of the environment. Thus, the entropy of the system increases due to the spontaneous process of salt dissolving in water.
