How is the volatility of a substance related to the intermolecular forces present within the substance? how is the volatility of a substance related to the intermolecular forces present within the substance? the weaker the intermolecular forces, the more likely it is that molecules are to evaporate at a given temperature, making the liquid more volatile. the volatility of a substance does not depend on the intermolecular forces present within the substance. the stronger the intermolecular forces, the more likely it is that molecules are to evaporate at a given temperature, making the liquid more volatile?
