Presentation Transcript

  1. Energy Conversions

  2. Electromagnetic energy is converted into chemical energy of the ‘food’ made by the plant and also the ‘burnable’ plant material. Sun shining on plants

  3. Gasoline (chemical energy) transfers to mechanical energy some electrical and much thermal energy. Car moving

  4. Electrical energy is converted to mechanical energy and thermal energy. Fan turning

  5. Chemical energy (food) is converted to mechanical energy and thermal energy. Persons running

  6. Electrical energy is converted to electromagnetic light waves and thermal energy. Lamp shining. All these colors are in visible white light.

  7. Chemical energy (wick and wax) are converted to electromagnetic light waves and thermal energy. Candle burning lipid

  8. Mechanical energy is converted to electrical energy and thermal energy. Dam and water

  9. toaster • Electrical energy is converted to electromagnetic light waves and thermal energy.

  10. Mechanical energy is converted to thermal energy. Flowing river

  11. Mechanical energy changes direction to continue mechanical energy but with the loss of thermal energy. Water windmill

  12. Mechanical energy is converted to electrical energy and thermal energy. Windmill turbine

  13. Electromagnetic energy is converted to electrical energy and thermal energy. Solar panels Our solar panels on Schweitzer.

  14. Electromagnetic energy is converted to chemical energy. Then chemical energy is converted to mechanical energy and thermal energy. Venus Fly Trap

  15. Chemical energy from the food is converted to mechanical energy and thermal energy. Animals running

  16. Chemical energy from the food is converted to mechanical energy and thermal energy. Fish swimming

  17. Chemical energy from the diesel is changed to mechanical energy and thermal energy. Tractor plowing field

  18. 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. Steam turbine

  19. Chemical energy (airplane fuel) is converted to mechanical energy and thermal energy. Airplane flying

  20. Nuclear fission is converted to thermal energy which moves water (steam) as mechanical energy, which turns magnets to make electrical energy and thermal energy. Nuclear power plant

  21. Chemical energy is converted into electromagnetic (light waves) and thermal energy. Fire fly or any other luminescent organism

  22. Electrical energy is being converted into some chemical energy and thermal energy….but not all the chemical reactants respond over time. Rechargeable batteries being recharged

  23. Mechanical energy from the river transfers in direction to continue mechanical energy and thermal energy. Old fashioned Saw MILL

  24. 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. Refrigerator

  25. Mechanical energy is converted to another material (mechanical) and releases some thermal energy. Flag blowing in wind
