The correct answer is this: THEY WILL BREAK DOWN.
In chemistry, entropy is defined as the degree of disorderliness or randomness of a system. Entropy has to do with the second law of thermodynamic, which relates to how energy spread out. The entropy of a system can be positive or negative depending on the direction of flow of energy. In positive entropy, the degree of disorderliness increases while in negative entropy the degree of randomness decreases. A positive entropy will always leads to the breakdown of the affected molecules.
