State whether the following statement is true or false:
When energy changes from one form to another,the energy that disappears from one form reappears in an exactly equivalent amount in the other form.
When energy changes from one form to another,the energy that disappears from one form reappears in an exactly equivalent amount in the other form.
(TRUE) The statement is True.
This is a fundamental principle known as the Law of Conservation of Energy.
According to this law,energy can neither be created nor destroyed,only transformed from one form to another.
Therefore,the total energy of an isolated system remains constant,meaning the amount of energy lost by one form is exactly gained by the other form.
