True or False questions: 1. During the absorption process, temperature has little effect on the partial pressures of water and ammonia, but it has a significant impact on the partial pressure of carbon dioxide. ( ) 2. After absorbing ammonia, the volume of brine increases, thereby increasing the solubility of sodium chloride. ( ) 3. Ammonia has a high solubility in brine; the process of ammonia absorption is mainly controlled by liquid film resistance. ( )
1. During the absorption process, temperature has little effect on the partial pressures of water and ammonia, but a significant effect on the partial pressure of carbon dioxide. ( Correct ) 2. After absorbing ammonia, the volume of brine increases, thereby increasing the solubility of sodium chloride. ( Incorrect ) 3. Ammonia has a high solubility in brine; the process of ammonia absorption is mainly controlled by liquid-film resistance. ( Wrong )
