Homework Help: Physical Science

The physical properties of ice are different from the physical properties of dry ice (frozen carbon dioxide). But the physical properties of gaseous water vapor and the physical properties of gaseous carbon dioxide are the same. Why?

A.) The valence electrons are more tightly bound to the atom in the solid form.

B.) The molecules have less kinetic energy in the solid form, so they don't interact as much.

C.) The molecules are so far apart in the gaseous form that they never interact with each other.

D.) The molecules in the solid form combine to form a crystal.

PLEASE HELP! I cant find any information on the properties!
