When I examine the temperature contour of the mixture of air vapor and liquid water, I notice that it eventually reaches the temperature of the bottom wall. This makes me believe that the air temperature is also decreasing. 

I'm also unsure about whether fog is being created. Does the creation of fog result in a change in the volume of liquid near the upper wall(away from the bottom wall), changing it from its initial value of 0 to a certain amount?
