For air with a relative humidity of 80%,a)the dry bulb temperature is ...
We know that for saturated air, the relative humidity is 100% and the dry bulb temperature, wet bulb temperature and dew point temperature is same. But when air is not saturated, dew point temperature is always less than the wet bulb temperature.

For air with a relative humidity of 80%,a)the dry bulb temperature is ...
Relative Humidity and Temperature Relationship:
Relative humidity is a measure of the amount of moisture present in the air compared to the maximum amount the air can hold at a specific temperature. In the case of air with a relative humidity of 80%, it means the air is holding 80% of the maximum amount of moisture it can hold at that temperature.

Dew Point Temperature:
The dew point temperature is the temperature at which air becomes saturated with moisture, leading to the formation of dew. It is the temperature at which the air can no longer hold all the moisture it contains, causing condensation.

Wet Bulb Temperature:
The wet bulb temperature is the temperature at which a wet surface exposed to the air reaches equilibrium. It is a measure of the cooling effect of evaporation and can be lower than the dry bulb temperature due to the cooling effect of evaporation.

Explanation of the Correct Answer:
In the given scenario where the relative humidity is 80%, the dew point temperature is less than the wet bulb temperature. This is because the wet bulb temperature accounts for the cooling effect of evaporation, which can make it lower than the dry bulb temperature. However, the dew point temperature is the temperature at which the air becomes saturated with moisture, leading to condensation. Therefore, in this case, the dew point temperature is lower than the wet bulb temperature, making option 'C' the correct answer.
