If a 2.75 L gas sample is held at a constant temperature, and its pressure is changed from 750.0 torr to 360.0 torr, what will the final volume be?

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.
