In a system, when potential energy decreases, then entropy also decreases. true false

False

Explanation:

The potential energy is called organized energy because it is not related to the mass movement of the molecules.

Heat is disorganized energy because it is related to the mass movement of the molecules. Entropy is related to the randomness of the molecules.

If the randomness of the system increases then the entropy will increase. The entropy of the system either remains constant or increases.

The entropy of the system never decreases.

Therefore, the answer will be false.

d is the correct answer

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.
