Document Summary
Thermochemistry: petrucci, herring madura and bissonnette : Problem set: chapter 7, questions: 6, 19, 41, 47, 57, 58, 74, 91. Thermochemistry: the study of energy in chemical reactions, a sub-discipline of thermodynamics, thermodynamics studies the bulk properties of matter and deduces a few general laws. It does not require any knowledge/assumptions of molecules. The part of the universe we chose to study: surroundings. The rest of the universe (normally we only worry about the immediate surroundings: process. A physical occurrence (usually involving energy flow) A system where energy and matter can be exchanged with the surroundings: closed system. A system where energy but not matter can be exchanged with the surroundings: isolated system. A system where neither energy nor matter can be exchanged with the surroundings. Systems and energy: all systems will contain energy. In thermodynamics we are interested in the flow of energy, particularly in the forms of heat and work.
