That means that there is 100% humidity. Normally evaporation from the wet bulb keeps its temperature lower than the dry bulb. At 100% humidity, there would be no evaporation, so they would show the same temperature.
-9c
for air water system wet bulb equals to dry bulb at 100 % relative humidity for that given temperature of air.
yes
-17
because the water causes the temperature to be lower
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.

the evaporation off the moisture on the wet bulb absorbs the heat.

Because the process of evaporation absorbs heat from the bulb.
Evaporation of the water in the wet bulb fabric cover causes the temperature of the wet bulb to go down. When the air is dry, more water will evaporate, and when the air is saturated, less will evaporate.
No. The temperature of dry ice is far lower than that of ice water.

When the humidity in the surrounding air is low, the water in the wet cloth wrapped around the bulb of the "wet bulb" thermometer evaporates quicker, giving lower reading on that thermoneter, thus widening the gap between the wet bulb and dry bulb temperatures. The lower the humidity in the air, the quicker the evaporation, the lower the "wet bulb temperature".
