what is the mathematical relationship present between temperature and volume using either a equation with T1, V1 and T2, V2 or a proportional statement?

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.

Answerionic bond imfs are stronger than covalent;
