Energy in a system can be transformed from one state to another. Which statement is true for all energy transformations? *
A-Total energy in a system remains constant.                            B-There must be an input of chemical energy for a transformation to occur.                                                                C-Electrical energy is always converted to mechanical energy.                                                                   D-Total energy in a system either increases or decreases.
