The direct answer to your question is that evolution does not violate the second law of thermodynamics at all. I have talked with many creationists, and I have never come across one who actually had an accurate understanding of what the second law says. The second law of thermodynamics says that entropy will never decrease in a closed system. Creationists paraphrase this as meaning that "systems tend towards disorder". (which is incorrect). The reason some creationists think that evolution violates this law is that they misunderstand its meaning in two different ways: 1) The term "entropy" is often taught to beginning students as meaning "disorder", and although this is a useful way to think of it, they are really not the same thing. Entropy and disorder correspond to each other in many different circumstances, but entropy is a thermodynamic quantity that has a precise mathematical definition. You cannot use the terms "entropy" and "disorder" interchangeably, and most creationists do exatly that in their arguments. 2) More importantly, creationists completely miss a crucial phrase in the second law..... "IN A CLOSED SYSTEM". The seond law makes a statement ONLY about closed systems.... open systems are free to increase or decrease their entropy, and it has no bearing on the validity of the second law. Since life is an open system (it receives energy from the earth and the sun), there is no problem at all with living systems decreasing their entropy (i.e., becoming more ordered in a thermodynamic sense). So the short answer to your question is that creationists think evolution violates the second law of thermodynamics because they want it to, and if they hear otherwise, they take measures to keep themselves willfully ignorant.

well, here it goes:
If some quantity of heat is supplied to a system capable of doing work, then the quantity of heat absorbed by the system is equal to the sum of the increase in internal energy and the external work done by the system
In other words, Let me explain in a very simplified manner with an example.
Take a sealed, perfectly conducting, cylindrical vessel, fully filled with neutral gas. The gas is now capable of doing work, if energy is supplied to it. Now heat it (energy is being supplied). The gas molecules gain energy, and get more active, but the pressure is not increased at all(this is called internal energy of the gas, or is also called Entropy. As u heat more and more, the cylinder becomes hot, and the pressure also increases(External work is done here). When pressure increases, temperature also increases( this is called enthalpy), and this process is simply called as the first law of thermodynamics.
Did u know that there is also ' Zero-th Law of thermodynamics, and Secomd Law of thermodynamics too?, well, Just thought u should know them too, to understand the principle of thermodynamics, Which stands for "Thermos - Heat" and "Dynamics - Motion" . So, thermodynamics stands for " Branch of science, which deals with all the principles associated with heat in motion".
Hope I helped you.

The laws of thermodynamics, in principle, describe the specifics for the transport of heat and work in thermodynamic processes.
First law of thermodynamics
“ In any process, the total energy of the universe remains constant. ”
More simply, the First Law states that energy cannot be created or destroyed; rather, the amount of energy lost in a steady state process cannot be greater than the amount of energy gained.

If you sum up all the energies in the universe to a single number it's a constant.
