1.	What is the average distance between atoms (interatomic distance) in water? Use the data given in Examples 13.1 and 13.2.
Answer» Solution :A given mass of WATER in vapour state has `1.67 xx 10^(3)` TIMES the volume of the same mass of water in liquid state . This is also the increase in the amount of volume available for each molecule of water. When volume INCREASES by`10^(3)`times the radius increases by `V^(1//3)` or 10times, i.e., `10 xx 2 À = 20 Å`. So the average DISTANCE is `2 xx 20 = 40 Å`.
