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 %.
