5,148。Estimate the distance (in nandQineters) between mol-
ecules of water vapor at 100。C and 1.0 atm. Assume
ideal behavior. Repeat the calculation for liquid
Water at 1005C, given that the density of water 1s
0.96 g/cm at that temperature. Comment on your
Tesults. (Assume water molecule to be a sphere With
