change in entropy total

why is the total change of entropy not always 0?

The total change of entropy is not always 0 because there is always disorder in a system. The only time that entropy is 0 is when the temperature in kelvin is going to 0 K.

Also, with q/T, if there's any heat transfer, there must be some change in entropy.
