Document Summary

The study of energy in chemical reactions. 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 choose to study. The rest of the universe (normally we only worry about the immediate surroundings) A physical occurrence (usually involving energy flow) If a system is open, energy and matter can be exchanged with the surroundings. A system where the energy but no matter can be exchanged with the surroundings. A system where neither energy nor matter can be exchanged with the surroundings. In thermodynamics, we are interested in the flow of energy, particularly in the forms of heat and work. Note that heat and work occur when there is a process. The system has energy, (often described as the capacity to do work), it does not have heat or work.
