Knowing the Van der Waals constant, find : (a) the maximum volume which water of mass `m = 1.00 kg` can occupy in liquid state , (b) the maximum pressure of the saturated water vapour. |
|
Answer» (a) The ciritical Volume `V_(MCr)` is the maximum volume in the liquid phase and the minimum volume in the gaseous. Thus `V_(max) = (1000)/(18) xx 3 xx .030 litre ~~ 5 litre` (b) The critical pressure is the maximum possible pressure in the vapour phase in equilibrium with liquid phase. Thus `p_(max) = (a)/(27 b^2) = (5.47)/(27 xx .03 xx .03) = 225 atmosphere`. |
