Document Summary

Thermochemistry: petrucci, herring madura and bissonnette : Questions: 6, 19, 41, 47, 57, 58, 74, 91. Thermochemistry: the study of energy in chemical reactions, relationship between heat and chemical and physical changes, heat and its measurement, the transfer of energy, internal energy and enthalpy. 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. Energy is the capacity to do work. In thermodynamics we are interested in the flow of energy, particularly in the forms of heat and work.
