Question

according to the concept of entropy, what will likely happen to most molecules over time? they will collect into an organized pile. they will turn into oxygen molecules. they will break down. they will combine to form larger molecules.

Explanation:

Entropy is a measure of disorder. Over time, systems tend to move towards higher entropy. Molecules will break down to increase disorder rather than form organized piles or larger molecules. There's no indication they'll turn into oxygen molecules specifically.

Answer:

They will break down.
