Final answer:The correct option is a.The human bodyutilizessweating as a cooling mechanism primarily due to the energy used during the process of evaporation. As water in the sweatevaporates, it draws heat away from the body. This cooling effect is influenced by relative humidity and relies on water's properties as a solvent.Explanation:Sweating is an important cooling mechanism for humans due to the significant amount of energy required for water to change from its liquid state to its gaseous state. This process, known asevaporation, happens when sweat is produced. The energy used to break the hydrogen bonds in water draws heat away from the body, cooling it in the process. Also, an element of water's cooling capability comes from its capacity to function as a heat sink, absorbing and dissipating heat without a corresponding rise in its own temperature.Evaporation's impact on cooling can be affected by environmental factors, such asrelative humidity. Sweat evaporates more quickly in lower humidity environments, which increases the rate of cooling. However, in high humidity, the air is already close to saturation with water so evaporation of sweat is far less efficient.Finally,water, due its polar nature and capacity to dissolve other polar molecules and ionic compounds, is an excellent solvent. Although this doesn't directly relate to cooling, it's crucial to the overall function of the body and the distribution of substances necessary for body temperature regulation.Learn more about Evaporation and body cooling here:brainly.com/question/20000785#SPJ2...
