Document Summary

Chapter 3 - part 2. Wednesday, september 30, 2015. Energy can enter and leave a closed system! Systems show several basic properties. Dynamic equilibrium - systems are constantly changing, interacting, balancing. Systems are always moving, energy comes in driving processes, form changing, balancing/rebalancing in diff parts of the system. Homeostasis - many systems tend to maintain stable internal conditions (=resistance) System has a tendency to want to maintain the same state. Her push example, disturbance knocked her out and resilience got her back up) Important in natural systems, this is what we want! (ability to come back) Resilience - some systems (not all) recovery easily from disturbances. Emergent properties - systems characteristics not evident in individual components on their own. System characteristics not evident in individual components on their own. A system of two or more connected reservoirs, in which material (or energy) is transferred in a cyclical fashion.
