10 Its of an air sample with relative humidity 0.6 is compressed to 5 litres at same temperature. What is the partial pressure of the water vapour in the compressed air, if the pressure of saturated water vapour at that temperature is 2.4 K Pa 

Options

A. 1.2 KPa
B. 2.4 Kpa
C. 3.6 kPa
D. 1.8 KPa

Explanation

`R.H. = 0.6 = (P_(H_2 O))/(V.P) xx 100`
`implies P_(H_2 O) = 0.6 xx 2.4 = 1.44 kPa`
on making volume half, `P_(H_2 O)` should double, but R.H. `> 100% implies` saturation.
`implies P_(H_2O) = 2.4 kPa` (limiting value) .
