AI Generated Solution

To find the change in internal energy (ΔU) when 2.0 moles of liquid water vaporizes at 100°C, we can use the relationship between the heat of vaporization (ΔH) and the change in internal energy (ΔU). The relevant equation is: \[ \Delta H = \Delta U + \Delta n_g RT \] Where: - ΔH is the heat of vaporization ...
