Based on the second law of thermodynamics, how would you expect a system to change over time?
a. it would become more organized
b. its randomness would increase
c. it would become more efficient
d. its energy would increase

B. Its randomness would increase

Explanation:

According to the second law of thermodynamics:  

"The amount of entropy in the universe tends to increase over time"

That is, in any cyclic process, entropy will increase, or remain the same.

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 (or randomness) of a system and is a function of state.
