Answer: 5) The second law of thermodynamics
Explanation:
According to the second principle of thermodynamics:
"The amount of entropy in the universe tends to increase over time"
So, in this context, entropy is a thermodynamic quantity defined as a criterion to predict the evolution or transformation of thermodynamic systems. In addition, it is used to measure the degree of organization of a system.
In other words: Entropy is the measure of the disorder of a system and is a function of state.
