Freon−12 (cf2cl2), widely used as a refrigerant and aerosol propellant, is a dangerous air pollutant. in the troposphere, it traps heat 25 times as effectively as co2, and in the stratosphere, it participates in the breakdown of ozone. freon−12 is prepared industrially by reaction of gaseous carbon tetrachloride with hydrogen fluoride. hydrogen chloride gas also forms. how many grams of carbon tetrachloride are required for the production of 47.6 dm3 of freon−12 at 25°c and 1.84 atm?

Relative humidity is low .

Explanation:

The wet bulb reads low temperature because due to low humidity of atmosphere , evaporation of water takes place from the wet bulb which makes the bulb cool and therefore it reads lower temperature . In the process of evaporation , heat equal to latent heat of vaporization is taken from the bulb and it loses temperature.
