Consider the following statements: In a chemical dehumidification proc...
Explanation:
Chemical dehumidification is a process used to reduce the moisture content in the air. This process involves the use of a chemical desiccant which absorbs moisture from the air. The following statements describe the changes that occur during the chemical dehumidification process:

1. DPT decreases:

The Dew Point Temperature (DPT) is the temperature at which the air becomes saturated with moisture. During the chemical dehumidification process, the desiccant absorbs moisture from the air, which causes the DPT to decrease.

2. WBT decreases:

The Wet Bulb Temperature (WBT) is the temperature measured by a thermometer with a wet wick wrapped around its bulb. It indicates the lowest temperature that can be achieved by evaporative cooling. During the chemical dehumidification process, the desiccant absorbs moisture from the air, which reduces the amount of moisture available for evaporative cooling. As a result, the WBT decreases.

3. DBT decreases:

The Dry Bulb Temperature (DBT) is the temperature of the air measured by a thermometer without a wet wick. During the chemical dehumidification process, the desiccant absorbs moisture from the air, which causes the air to cool. As a result, the DBT decreases.

Therefore, the correct statements are 1 and 2, which are that the DPT and WBT decrease during the chemical dehumidification process. Statement 3, that the DBT decreases, is incorrect, as the air cools during the process, but the DBT remains the same. Hence, the correct option is B.
