If you are referring to using a surface thermometer, no.
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.

The evaporation of water from the cloth lowers the temperature of the cloth and thus hopefully by conduction the temperature of the person. Note that this method does not work in spaces with 100 % relative humidity.

Yes, the wet bulb on a Wet Bulb Globe Temperature (WBGT) device should be wetted with distilled water to ensure accurate readings. Using distilled water helps prevent any impurities that may affect the measurement. It ensures the wet bulb accurately reflects the evaporative cooling effect.
The relative humidity is 100% because the dry-bulb temperature and wet-bulb temperature are the same, indicating that the air is saturated with moisture and cannot hold any more water vapor.
Wrapping cotton wool around a thermometer can cause the temperature reading to drop because cotton wool is a good insulator. It prevents heat from reaching the thermometer, resulting in a lower temperature reading.
Why is the wet-bulb reading necessary when checking the charge
If the outside temperature gauge is not reading the right temperature on a Buick Regal, perhaps it has become damaged. It can also not read the right temperature if it is wet or covered with dirt or snow.
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".
Doctors advise placing strips of wet cloth on the forehead of a patient with a high fever to help cool the body down through evaporation. The moisture from the cloth absorbs heat from the skin as it evaporates, providing a cooling effect. This method can also offer some comfort to the patient while helping to lower their body temperature. However, it's important to monitor the patient's condition and seek medical attention if the fever persists.
