Crystalline and amorphous solids differ in the degree of order among their particles.

True
False

If the rate of melting and the rate of freezing were the same, we could say there is a dynamic equilibrium of the system.

True
False

The reason the vapor pressure increases with increasing temperature is due to the increased kinetic energies of the gas molecules.

False

true to all of them

Careful.  I suspect the answer wanted for the last one might be "false," because it refers to the kinetic energy of the GAS molecules -- not the molecules of the liquid.
