Which of the following molecules has the higher AHvap (the amount of energy needed to change the substance from a liquid to a gas) and why? B They both have the same AHvap, because they have the same type of intermolecular force. AHvap is temperature dependent, so it depends on the temperature. A, because it has stronger intermolecular forces, requiring more energy to overcome the intermolecular forces. B, because it has stronger intermolecular forces, requiring more energy to overcome the intermolecular forces. Not enough information is given.
