With rise in temperature, the solubility of ammonia in water at a fixed pressure
-
If the pH value of a solution changes by one unit, it implies that hydrogen ion concentration in the solution will change __________ times.
-
The temperature at which a real gas obeys Boyle's law is termed as the

Heat of neutralisation of HCl and NaOH is - 57.46 kJ/Kg mole. The heat of ionisation of water will be __________ kJ/Kg mole.
-
A vessel of volume 1000 m3 contains air which is saturated with water vapour. The total pressure and temperature are 100 kPa and 20°C respectively. Assuming that the vapour pressure of water at 20°C is 2.34 kPa, the amount of water vapour (in kg) in the vessel is approximately
