Energy is conserved so orderly or chaotic the energy of a system always remains the same, but the entropy does not, it always increases. Two systems may have equal energy but you can extract more work out of a low entropy system than a high one. Work means a force applied over a distance so entropy can be thought of as the ability a system has to concentrate its energy. A box of very hot gas would have lot of energy, the atoms in the gas would be moving very rapidly, but if it was all at the same temperature the gas would have a high entropy and thus there would be no way to make those atoms to team up and move in just one direction and do some work. But if the left half of the box had hot atoms and right half cold atoms then it would have low entropy and you get things to move in one particular direction and do work. > > > Your cigarette smoke example, is caused by the dissipated smoke colliding > with random (hee hee) air currents. > Air currents are not random, but the vibration of air molecules is. > Even the randomness of a program's random number generator was designed. No program can produce true randomness, for that you need hardware that obeys the laws of physics.
