Entropy is the measure of ored and disorder. But who tells that what is order and what is disorder? Isnt it a relative or subjective thing? How to define it in general, or it can be definet only for thermodinamic systems?
Entropy is a measure of the disorder or randomness in a system. It is a thermodynamic property that describes the amount of energy that is unavailable for work in a system.
In general, a system with high entropy is considered to be more disordered, while a system with low entropy is considered to be more ordered. This is because as a system becomes more disordered, the number of possible arrangements or microstates that it can exist in increases, leading to a higher entropy value.
Some examples of systems with high entropy include a gas that has expanded to fill a large volume, a disorganized pile of books, or a cup of hot coffee that has cooled to room temperature.
The second law of thermodynamics states that the total entropy of a closed system will always increase over time. This means that natural processes tend to move towards a state of higher entropy and disorder.
While it is possible to decrease the entropy of a system in a localized area, the overall entropy of the system and its surroundings will always increase due to the second law of thermodynamics. This means that overall, entropy cannot be reversed or decreased in a closed system.
