Answer:
B. A pile of dirt on the floor is cleaned up with a broom.
Explanation:
An increasing entropy is something that is left to be, like the other answers. decreasing entropy is disrupted usually by a person or something living.
When the pile of dirt on a floor is cleaned up with a broom, the molecular weight of the dirt present on the floor will decrease resulting in a decreased entropy.
Entropy is the measure of the degree of disorderliness of a system. It entails the randomness of a system.
- Entropy of a system increases with increase in temperature and molecular weight of the compound.
- Entropy can also increase when the pressure of the system is reduced.
A decrease in entropy would mean an increase in pressure, or a decrease in molecular weight or temperature.
Thus, considering the given options, only option B will result in a decreased molecular weight. When the pile of dirt on a floor is cleaned up with a broom, the molecular weight of the dirt present on the floor will decrease resulting in a decreased entropy.
