Question
According to the law of conservation of energy:
- Energy can't be destroyed.
- Energy can't be created.
- Energy can be transformed from one form to another
- All the above
Hint:
This law is derived from the first law of thermodynamics.
The correct answer is: All the above
According to the law of conservation of energy: All of the above statements are true.
- Energy can't be created, Energy can be transformed from one form to another, and Energy can't be destroyed.
- Energy conservation law specifies that energy can neither be generated nor wasted- it can only be transferred from one source of energy to another/ one form to other.
- Which means whether it is applied from the outside, a system still has the same amount of energy.
