ANS:B - more than

The dry bulb temperature of the gas is more than the wet bulb temperature. The dry bulb temperature refers to the temperature measured by a thermometer when no moisture is evaporating from the thermometer bulb. It represents the actual temperature of the air. The wet bulb temperature, on the other hand, is measured by a thermometer with its bulb covered by a wetted wick or cloth. As water evaporates from the wetted surface, it cools the thermometer bulb, resulting in a lower temperature reading compared to the dry bulb temperature. Therefore, in general, the dry bulb temperature is higher than the wet bulb temperature.
