Suppose that 0.15 moles of some acid are added to a liter of water; both are initially at room temperature. The addition raises the temperature by 0.1 K. How much deeper is the potential well of the acid molecules when in water than when in the concentrated acid? (The heat capacity of a liter of water is 4186 J/K.) 19. From a molecular point of view, why is u0 for: (a) liquid water less (more negative) than that of water vapor? (b) ice less than that of liquid water? (c) salt in water less than that of salt in oil?
