Most important in this regard is the Second Law of Thermodynamics, which states that in any closed process, there is an increase in the total entropy (roughly speaking, a measure of disorder). The increase in disorder is the opposite of increasing order due to evolution, the creationists reason, ergo — a contradiction! Overlooking the crucial word “closed,” of course. There are various equivalent ways of stating the law, one of which is that energy cannot pass from a cooler to a warmer body without extra work being done. Ginsberg’s theorem (as in poet Allen Ginsberg) puts it like this: “You can’t win. You can’t break even. You can’t even get out of the game.” Although creationists have long mistakenly believed that evolution is a violation of the Second Law, actual scientists have not. For example, physicist Stephen G. Brush, writing for the American Physical Society in 2000, in “Creationism Versus Physical Science,” noted: “As Ludwig Boltzmann noted more than a century ago, thermodynamics correctly interpreted does not just allow Darwinian evolution, it favors it.”
A simple explanation of this comes from a document in the thermodynamics FAQ subsection of TalkOrigins Archive (the first and foremost online repository of reliable information on the creation/evolution controversy), which in part explains:
_
Creationists thus misinterpret the 2nd law to say that things invariably progress from order to disorder.
However, they neglect the fact that life is not a closed system. The sun provides more than enough energy to drive things. If a mature tomato plant can have more usable energy than the seed it grew from, why should anyone expect that the next generation of tomatoes can’t have more usable energy still?

That passage goes right to the heart of the matter. Evolution is no more a violation of the Second Law than life itself is. A more extensive, lighthearted, non-technical treatment of the creationist’s misunderstanding and what’s really going on can be found here.
