what does a high boiling point temperature indicate about a substance? a. the chemical bond energy within the substance is very high. b. little thermal energy has been added to the substance. c. the pressure over the liquid form of the substance is very low. d. the intermolecular forces within the substance take a lot of energy to overcome.
Answer
Brief Explanations:
The boiling - point of a substance is related to the strength of its intermolecular forces. Higher boiling points mean more energy is needed to separate the molecules from the liquid phase to the gas phase by overcoming these intermolecular forces. Chemical bond energy refers to intramolecular forces within a molecule, not related to boiling point in this context. Little thermal energy added would mean a lower temperature, not a high boiling point. Low pressure over a liquid lowers the boiling point, not raises it.
Answer:
D. The intermolecular forces within the substance take a lot of energy to overcome.
