What is the relative humidity on a day, when partial pressure of water vapour is 0.012 X 10 to the power of 5Pa and temperature is 12 degree celsius? The vapour pressure of water at this temperature is 0.016 x 10 to the power of 5Pa
1. 68%
2. 52%
3. 25%
4. 75%
Please explain the aswer as well.

Expert Answer:

begin mathsize 12px style Relative space humidity space is space defined space as straight R. straight H equals fraction numerator Partial space vapour space pressure over denominator Vapour space pressure space of space water space at space same space temperature end fraction cross times 100 percent sign It space is space given space that space partial space vapour space pressure space is space 0.012 cross times 10 to the power of 5 space Pa and space vapour space pressure space of space water space at space 12 space degree straight C space is space 0.016 cross times 10 to the power of 5 space Pa Hence comma space we space get straight R. straight H equals fraction numerator 0.012 cross times 10 to the power of 5 over denominator 0.016 cross times 10 to the power of 5 end fraction cross times 100 equals 12 over 16 cross times 100 equals 75 percent sign This space answer space means space that space the space air space is space 75 percent sign space moist. space That space is comma space the space water space content space in space air space is space 75 percent sign. end style
