Q1: At 100% relative humidity, the dew point temperature of moist air is

ANS:B - more than the wet bulb temperature.

the statement "more than the wet bulb temperature" is incorrect in the context of relative humidity and dew point temperature. The wet bulb temperature represents the lowest temperature to which air can be cooled by the process of evaporation of water into it, leading to saturation. At 100% relative humidity, the air is saturated with moisture, and the wet bulb temperature is equivalent to the dew point temperature. Therefore, in the context of 100% relative humidity, the dew point temperature is equal to the wet bulb temperature, not more than it. If the air is not saturated (i.e., the relative humidity is less than 100%), then the dew point temperature can be more than the wet bulb temperature. This occurs because the wet bulb temperature is influenced by the evaporative cooling effect, whereas the dew point temperature is solely dependent on the moisture content of the air. However, at 100% relative humidity, both temperatures are the same.
