The correct answer is option 'B': the dew point temperature is less than the wet bulb temperature.
Explanation:
To understand why the dew point temperature is less than the wet bulb temperature when the relative humidity is 80%, let's first define these terms:
- Dry Bulb Temperature: This is the temperature of the air measured using a regular thermometer. It represents the actual temperature of the air.
- Wet Bulb Temperature: This is the temperature of the air measured by placing a wet cloth around the bulb of a thermometer and allowing the water to evaporate. The wet bulb temperature is lower than the dry bulb temperature because of the cooling effect of evaporation.
- Dew Point Temperature: This is the temperature at which the air becomes saturated with water vapor and condensation begins to occur. It represents the temperature at which the air can no longer hold all the moisture it contains.
Now, let's consider the relative humidity of 80%. Relative humidity is a measure of the amount of moisture in the air compared to the maximum amount of moisture the air can hold at a particular temperature. At 80% relative humidity, the air is holding 80% of the maximum amount of moisture it can hold at that temperature.
When the air is at 100% relative humidity, it is saturated with moisture and the dew point temperature is equal to the dry bulb temperature. However, when the relative humidity is less than 100%, the dew point temperature is lower than the dry bulb temperature.
In this case, the relative humidity is 80% which means the air is not fully saturated. Therefore, the dew point temperature will be lower than the wet bulb temperature because the wet bulb temperature takes into account the cooling effect of evaporation. The wet bulb temperature will be closer to the dry bulb temperature, but still lower due to evaporation.
Therefore, the correct answer is option 'B': the dew point temperature is less than the wet bulb temperature.
