A balloon is filled to a volume of 17L at a temperature of 39°C. The balloon is then cooled at constant pressure to a temperature of -28°C. What is the final volume of the ballon?

You need to divided twenty four by a dozen them by the temperature it is getting cook by

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.
