Answer:
Entropy is the reason of worrying about world energy sources.
Step-by-step explanation:
- Entropy is the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work.
- The amount of entropy is also a measure of the molecular disorder, or randomness, of a system.
- For example , There are some reactions which are irreversible because some of the energy in the reaction is lost to environment instead of converting totally to the products.
- This lost of energy is entropy.
- Due to which the energy of universe is losing irreversibly.
- That's why we worry about world energy sources.
