Question:
Which of the following statement is true?
a) Dew point temperature is the temperature at which water vapour starts condensing.
b) Dry bulb temperature is recorded by thermometer with dry bulb.
c) Wet bulb temperature is recorded by thermometer when bulb is covered with a cotton wick which is saturated with water.
d) All of the mentioned.
Answer amd explanation:
d) All of the mentioned statements are correct.
Dew point is the temperature at which condensation happens. Dew litteraly means condensed water in atmosphrere
Dry bulb temperature is recorded by thermometer with dry bulb. This statement is correct because it refers to the ambient air temperature. It is called "Dry Bulb" because the air temperature is indicated by a thermometer not affected by the moisture of the air.
Wet bulb temperature is recorded by thermometer when bulb is covered with a cotton wick which is saturated with water. This statement is correct because the less moisture in air hepls the water more rapidly on the wet cloth to evaporate, and the cooler the wet bulb temperature will be.
So all of the above mentioned statements are correct.
