									Energy Conversions
Sun shining on plants
           Electromagnetic energy
             is converted into
             chemical energy of
             the ‘food’ made by the
             plant and also the
             ‘burnable’ plant
             material.
Car moving   Gasoline (chemical energy)
               transfers to mechanical
               energy some electrical
               and much thermal
               energy.
Fan turning
      • Electrical energy is
        converted to
        mechanical energy
        and thermal energy.
Persons running
        • Chemical energy
          (food) is converted to
          mechanical energy
          and thermal energy.
Lamp shining.
       • Electrical energy is
         converted to
         electromagnetic light
         waves and thermal
         energy.




        All these colors are in visible white light.

       • Mechanical energy is
         converted to thermal
         energy.
Water windmill
       • Mechanical energy
         changes direction to
         continue mechanical
         energy but with the
         loss of thermal
         energy.
Windmill turbine
         • Mechanical energy is
           converted to electrical
           energy and thermal
           energy.
Solar panels
            • Electromagnetic
              energy is converted to
              electrical energy and
              thermal energy.




 Our solar panels on Schweitzer.
Venus Fly Trap
       • Electromagnetic
         energy is converted to
         chemical energy.
       • Then chemical energy
         is converted to
         mechanical energy
         and thermal energy.
Animals running
         • Chemical energy from
           the food is converted
           to mechanical energy
           and thermal energy.
Fish swimming
       • Chemical energy from
         the food is converted
         to mechanical energy
         and thermal energy.
Tractor plowing field
           • Chemical energy from
             the diesel is changed
             to mechanical energy
             and thermal energy.
Steam turbine
       • Chemical energy of
         fuel converts to
         thermal energy that
         moves water into
         mechanical energy
         which turns magnets
         to move electrons
         (that is: make
         electrical energy) and
         thermal energy.
              Airplane flying




Chemical energy
 (airplane fuel) is
 converted to
 mechanical energy
 and thermal energy.
Nuclear power plant
           • Nuclear fission is
             converted to thermal
             energy which moves
             water (steam) as
             mechanical energy,
             which turns magnets
             to make electrical
             energy and thermal
             energy.
Fire fly or any other luminescent
             organism
        • Chemical energy is converted
          into electromagnetic (light
          waves) and thermal energy.
Rechargeable batteries being
        recharged
              • Electrical energy is
                being converted into
                some chemical
                energy and thermal
                energy….but not all
                the chemical
                reactants respond
                over time.
Old fashioned Saw MILL

           • Mechanical energy
             from the river
             transfers in direction
             to continue
             mechanical energy
             and thermal energy.
Refrigerator
      • Electrical energy is
        converted into
        mechanical energy and
        thermal energy.
      • The pump ‘compresses’
        the coolant so it can then
        ‘decompress’ under the
        refrigerator to release its
        heat that it pickup from
        the warm food we placed
        inside.
Flag blowing in wind
          • Mechanical energy is
            converted to another
            material (mechanical)
            and releases some
            thermal energy.
