In this context, a "system" is a collection of things around which you draw a notional boundary. You watch what comes in or goes out through the boundary over time. You can ask questions about the state of the system.shihab-kol said:OK, so what do you mean by 'system' ?
I did not understand your first question.
shihab-kol said:From what I know, the law says that disorder increases over time.
But, when a building is constructed the disordered bricks,cement etc. take form of the ordered building.
Am I wrong or is this an exception?
You need to know the concept of a system to do any physics. A system is a defined boundary containing some configuration of matter and energy. The configuration of the matter and energy is known as the state of the system. Physics is largely a process of keeping track of the matter and energy that crosses the boundary of a given system and applying laws that allow you to predict how the system changes state.shihab-kol said:OK, so what do you mean by 'system' ?

The second law of thermodynamics is a fundamental law of physics that states that the total entropy of a closed system will always increase over time, or remain constant in ideal cases where the system is in a steady state or undergoing a reversible process. In simpler terms, it means that the natural direction of any physical process is towards disorder and randomness.
Entropy is a measure of the disorder or randomness of a system. The second law of thermodynamics states that the total entropy of a closed system will always increase over time, meaning that the disorder or randomness of the system will also increase. This is because energy tends to disperse and become more evenly distributed, leading to a more chaotic and disordered state.
No, the second law of thermodynamics is a fundamental law of physics and cannot be violated. It is a principle that has been observed and tested in countless experiments and has never been found to be untrue. However, there are certain situations where it may appear to be violated, but these are usually due to incomplete knowledge or understanding of the system.
Living organisms are open systems that constantly exchange energy and matter with their surroundings. The second law of thermodynamics applies to living organisms in that they also tend to move towards disorder and randomness. However, living organisms are able to maintain their internal order and complexity by constantly taking in energy and converting it into useful work.
Some real-world examples of the second law of thermodynamics include a cup of hot coffee cooling down, a car engine producing heat and waste gases, and a room becoming messier over time. These processes all involve energy being converted from a more organized form to a more disordered form, in accordance with the second law of thermodynamics.
