What is the saturation temperature at the partial pressure of water vapour in the air water-vapour mixture called Correct Answer Dew point temperature

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.

Consider the following statements and choose the correct answer:
1. A direct proportionality exists between vapour pressure and the concentration of water vapour in the atmosphere
2. Relative humidity is an expression of the ratio of the actual vapour pressure of the atmosphere when saturated at the same temperature
3. A rise or fall in temperature with no change in vapour pressure will cause a drop or rise, respectively, in relative humidity
4. A rise or fall in vapour pressure with no change in temperature will be accompanied by a rise or fall, respectively, in relative humidity
Relative humidity is given by (where pv = Partial pressure of water vapour, pb = Barometric pressure, ps = Pressure of saturated air, pd = Pressure at dry bulb temperature, pw = Saturation pressure corresponding to wet bulb temperature, and μ = Degree of saturation)
