|
Energy can be created, just not destroyed. It changes its form from one type to another.
|
|
|
Energy can never be created nor destroyed. It can only change its form from one type to another.
|
|
|
The total energy in our Universe changes, as different forms of energies can be transformed from each other under certain circumstances.
|
|
|
Energy transformations do not passively occur in our lives, rather we actively make use of energies and transform energies.

Detailed explanation-1: -First law of thermodynamics states that total energy of an isolated system is constant, energy can neither be created nor be destroyed but can be transformed from one form to another.
Detailed explanation-2: -Yes, this is true according to law of conservation of energy, which says energy can neither be created nor be destroyed. It can only be transformed from one form to another. Whenever energy changes from one form to another, the total amount of energy remains constant.
Detailed explanation-3: -The first law of thermodynamics states that energy can neither be created nor destroyed, only altered in form. For any system, energy transfer is associated with mass crossing the control boundary, external work, or heat transfer across the boundary. These produce a change of stored energy within the control volume.
