What does it mean to say that in any system the total energy score stays the same?
The meaning of the statement that says that in any system, the total energy score stays the same.
Answer to Problem 12A
It means that the total energy of an isolated system always remains the same.
Explanation of Solution
Introduction:
As per law of conservation of energy, the energy of an isolated system cannot be destroyed or created. It always converts from one form to the another.
Since in an isolated system, the energy always converts from one form to the another, hence the total energy of the system always stays the same.
Conclusion:
Hence, in an isolated system, the total amount of the energy never changes.
