Answer:
The correct answer is -
a) The relative humidity decreases with an increase in temperature.
b) 25%
Explanation:
The dew point (Td) is the temperature at which the Relative humidity (RH) is 100%. So in the given question dew point, is (Td) is 7° C. The RH can be calculated by the formula:
[tex]RH: =100*\frac{(EXP((17.625*TD)/(243.04+TD))}{EXP((17.625*T)/(243.04+T)))}[/tex]
Putting the values of Td and T we get RH=
[tex]RH: =100*\frac{(EXP((17.625*7)/(243.04+7))}{EXP((17.625*29)/(243.04+29)))}[/tex]
= 25.02 or 25 %.
