Kinetic Molecular Theory?

Question

Benzoic acid, C6H5COOH, melts at 122 degrees C. The density in the liquid state at 130 degrees C is 1.08g/cm^3. The density of solid benzoic acid at 15 degrees C is 1.266g/cm^3.

In which state is the average distance between molecules the greatest?

Explain the difference in densities at the two temps in terms of the kinetic molecular theory.

Answer 1

Go to the reference web pages below. Browse the hyperphysics site to find the liquid & solid theory This is a great site. (Right now the site seems to be down so I couldn't locate the exact pages.)
