Vapour pressure deficit

The vapour pressure of water depends upon

Liquid-Vapour Equilibrium

A solution containing 30 gm of non-volatile solute exactly in 90 gm of water has a vapour pressure of 2.8 kPa at 298 K. Further, 18 gm of water is then added to the solution and the new vapour pressure becomes 2.9 kPa at 298 K.Calculate: (i) molar mass of the solute (ii) vapour pressure of water at 298 K.

The vapour pressure of water at 20°C is 17.54 mmHg. What will be the vapour pressure of thewater in the apparatus shown after the piston is lowered, decreasing the volume of the gasabove the liquid to one half of its initial volume (assume temperature constant).(A) 8.77 mmHg (B) 17.54 mmHg(C) 35.08 mmHg (D) between 8.77 and 17.54 mmHg

The ratio of partial pressure of the vapour in the gas mixture and the saturation vapour pressure of the vapour component is called Relative Humidity Specific Humidity Dry air pressure Humidity Rati
