Which of the following is the determination of the temperature at which the partial pressure of water vapor is equal to its saturation value? Correct Answer dew point measurement

Dew Point temperature: Dew point temperature is the saturation temperature corresponding to the partial pressure of water vapour. Dew point temperature is the temperature of air recorded by a thermometer when the moisture (water vapour) present in it just begins to condense.

Dry Bulb Temperature: Actual temperature of gas or mixture of gases.

Wet-bulb temperature: Temperature obtained by an accurate thermometer having a wick moistened with distilled water.
