Best ResponseYou've already chosen the best response.0hmm, well for vaporization the molecules need enough energy to overcome the intermolecular, attractive forces. Ice on the other hand does not need this energy to overcome attractive forces as they are still occur for liquids.

Best ResponseYou've already chosen the best response.0Well, how exactly do the molecules "overcome" the intermolecular forces? Do the bonds break?

Best ResponseYou've already chosen the best response.0It depends on the compound for "bonds". Water has Hbonds but helium has weak intermolecular forces and no "bonds" to break. As heat is added, it increases the kinetic energy (vibrational and such). This kinetic energy overpowers the intermolecular forces when it becomes a gas.
