1.	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
Answer» 1.2 KPa 2.4 Kpa 3.6 kPa 1.8 KPa SOLUTION :`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) .
