ISRO Technician-B MRAC Question Paper - 2017 (Set -1) with Answer Key

Dew point temperature is the saturation temperature corresponding to the partial pressure of the water vapour in moist air

Dew point temperature can be measured with the help of thermometer

Dew point temperature is the same as the thermodynamic wet bulb temperature

For saturated air, dew point temperature is less than the wet bulb temperature

It denotes the amount of water vapour actually present in air as a percentage of maximum amount that could be present at that particular temperature

It represents the ratio of mass of water vapour to the mass of dry air in a given volume of air water vapour mixture

It is the mass of water vapour per unit volume of air water vapour mixture

None of these

Wet bulb temperature

Specific humidity

Dew point temperature
