Question

What does "Energy of the system remains conserved" mean?

Answer 1

In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another.

Answer 2

energy can neither be created Nor be destroyed according to laws of conservation of energy.but it can be converted from one form to another.for example,mechanical energy can be converted into electrical energy.
