How is the entropy of the universe increasing when entropy is simply transferred?

For example, an increase in the entropy of the system will be exactly equal to the entropy decrease of the surroundings. So the net change in the entropy of the system and its surroundings is zero.
Putting this in perspective to all the systems and environments in our universe, how is the universe always increasing in entropy? Thanks in advance! ninjarawr

I'm not really sure the if the entropy of a system increases, the entropy of the surroundings will decrease. There's no conservation of entropylaw. If you have a closed system, it's entropy has nothing to do with the surroundings.

I think what may have confused you is that if you look at a 'nonclosed' system you can observe an entropy decrease, but this means that entropy somewhere else was increased.
So entropy is still increasing overall. Perhaps you read something like that and generalized it to a conservation law.. However, it doesn't work the other way around. So an entropy increase does not have to accompany an entropy decrease.

Fom Wikipwdia: "In systems held at constant temperature, the change in entropy, ΔS, is given by the equation
[tex] \Delta S = \frac{Q}{T} [/tex], where Q is the amount of heat absorbed by the system in an isothermal and reversible process in which the system goes from one state to another, and T is the absolute temperature at which the process is occurring." ehild
