Document Summary
Law of thermodynamics- energy does not disappear/consumed, just transformed and changes shape. Universal law of attraction- what is too much seeks to go towards what is too little . Energy transfer is shown in 3 types of systems: open, closed, isolated. Open can exchange both matter and energy within an outside system. Closed can exchange only energy within an outside system. Isolated doesn"t exchange either energy or matter within an outside system. Components system made up of diverse components that function as a whole. Equilibrium state state of the system that will not change unless there is a disturbance. Stable equilibrium state system will return to if disturbed slightly. Unstable equilibrium a small disturbance will carry the system away from one state to another. Threshold event small changes that causes the system to shift from one state to another. Disturbance perturbation temporary disturbance, ex volcano may change climate but it will return. Forcing a more persistent disturbance, ex global warming.
