is virtually wrong because the second law doesn't tell what happens to the entropy in non-isolated systems.It could be constant,increase,decrease,depends on the interactions between the studied system and the environment.misogynisticfeminist said:

The second law of thermodynamics states that in any energy conversion or transfer process, the total amount of energy remains constant, but the amount of usable energy decreases. This means that energy tends to disperse or become less organized over time.
The first law of thermodynamics, also known as the law of conservation of energy, states that energy cannot be created or destroyed, only transferred or converted from one form to another. The second law of thermodynamics expands on this by stating that while energy may be conserved, it becomes less usable over time.
Entropy is a measure of the disorder or randomness in a system. The second law of thermodynamics can be stated in terms of entropy as "the entropy of a closed system tends to increase over time." This means that as energy disperses and becomes less organized, the entropy of a system increases.
One example is the cooling of a hot cup of coffee. The heat energy from the coffee will eventually disperse into the surrounding environment, making the coffee cooler and less organized. Another example is the internal combustion engine, where the energy from burning fuel is converted into motion, but some of it is lost as heat and cannot be used again.
The second law of thermodynamics puts a limit on the efficiency of any energy conversion process. This is because some energy will always be lost as heat, which is a less usable form of energy. The more efficient a process is, the less energy is lost as heat and the closer it gets to achieving the maximum possible efficiency, known as the Carnot efficiency.
