                        3. Energy transfer
                          1. Energy can be transferred usefully, stored, or dissipated , but cannot be created or destroyed
                            1. When energy is transferred, only part of it may be usefully transferred; all other energy output is "wasted"
                              1. Wasted energy is eventually transferred to the surroundings , which become warmer. The wasted energy energy becomes increasingly spread out and so becomes less useful
                            2. Calculating Efficiency
                              1. Efficiency= useful energy out/ total energy in (*100%)
                                1. Efficiency= useful power out/ total power in (*100%)
