Make your studying easier with these chill class notes covering the Thermochemistry chapter in freshman Chemistry. Get cozy with the world of thermodynamics, heat transfer, and energy changes. Check out concepts like enthalpy, cool exothermic and endothermic reactions, some calorimetry vibes, Hess's Law for those who like shortcuts, and the First Law of Thermodynamics, which is basically energy's version of "What goes around comes around." These notes are your go-to for nailing the basics of the...

Chemistry Thermodynamics Study Guide What is the law of conversion of energy? - Energy is neither created or destroyed If a process's bonds are broken is the process endo- or exothermic? If a process is forming bonds is it endo- or exothermic? - Endothermic because breaking bonds takes energy. If a process is forming bonds it is exothermic. Where does the energy to break bonds come from in a chemical reaction? - The surroundings What does the term the system refer to? - Whatever you...
