This document discusses key concepts in thermochemistry including changes in enthalpy, thermochemistry equations, calorimetry, Hess's law, internal energy, and entropy. It was written by Putri Rosida R, ST and covers topics such as the equation for calorimetry calculations involving heat absorbed by a solution and calorimeter, and how Hess's law relates to changes in enthalpy for chemical reactions.
