Hey guys... I need serious help.
Question: explain and evaluate how water's ability to absorb heat is used to measure energy changes in chemical reactions. I need to design a first-hand experiment to measure the change in temperature when substances dissolve in water and describe how you calculate the molar heat of soloution.

Any ideas...?
