Conceptually, when there are looser bonds, the structure can vibrate more at lower temperature, so the heat capacity is greater for a given T. So the total energy that is needed to get the substance up to a given temperature is greater. The reason it is a rough indicator rather than a literal measure is because the first integral (the energy) is obviously much greater in magnitude (and in different units) from the second, which is the entropy. | |

How are the bonds related to the heat capacity? Also why is it a rough indicator and not to be taken too literal? | |
