  1. 1. Energy that comes from the movement of electrons
  2. 3. Discovered in 1932,This theory was theorized originally by James Chadwick. The theory states that matter is made up of tiny particles (or atoms & molecules), particles are in a constant state of motion, particles of matter are held together by attractive forces (strength of the force is entirely dependent on the type of molecule), particles have empty spaces between them that are much larger than themselves, particles from different substances have different properties than molecules from other substances, and that temperature affects the speed of the particles. Particles that are higher in temperature spin much faster than those that are cold,
  3. 5. A mechanical or electrical device for measuring temperature
  4. 6. The state at which a molecule is at. This can change at any given time.
  5. 10. Uses mechanical devices like fans and pumps to distribute stored thermal energy
  6. 12. Energy from the Sun (only available in daytime hours, becomes less common in winter, and is very clean and sustainable)
  7. 13. Solar Energy: Using materials in a structure to absorb solar energy, store it as thermal energy, and then release the thermal energy
  8. 16. The result of matter changing its shape, area, or volume as a response to temperature changes.
  9. 17. The direct transfer of thermal energy (kinetic energy) from one particle to the next
  10. 20. A unique temperature at which a substance melts/boils at
  11. 22. Forces that either push or pull a substance or object
  12. 23. The state of matter where the substance has a definite volume but no shape and particles inside of it move around freely.
  13. 25. The state of matter where the substance does not have a definite shape nor volume, and many of the electrons have been stripped from the atoms inside the substance.
  14. 27. Uses waste heat to generate electricity, heat buildings, etc
  15. 29. Energy stored in the chemical bonds of a substance
  16. 30. The energy a particle possesses because of its motion. The faster (or more random) a particle is moving the more kinetic energy it has.
  17. 31. Fuels are a type of chemical energy. It was considered unsustainable because it takes millions of years to replace.
  18. 32. The total kinetic energy of all particles in a substance
  19. 36. Energy changing from one form to another
  20. 39. Measuring temperature using thermometers or other temperature measuring devices
  21. 40. The transfer of energy without the use of any matter or molecules. This type of heat usually behaves like waves, and can travel across the vacuum of space at 300,00 km/s. These waves can bounce off objects or be absorbed by them

  1. 2. The measurement of heat using numbers
  2. 4. Devices that do NOT have digital components and sensors, and operate WITHOUT electricity.
  3. 7. A unit of temperature commonly used in the USA
  4. 8. Ex; A switch that turns your lightbulb on and off
  5. 9. Most scientists believe that the increased amounts of carbon dioxide and other greenhouse gasses produced by human activities are trapping thermal energy, warming the Earth at a fairly rapid rate
  6. 11. The energy transferred from one substance to another as a result of a temperature difference
  7. 12. Amount of thermal energy it takes to warm or cool one gram of a material by one degree celsius.
  8. 14. The state of matter where the substance was a definite shape and volume.
  9. 15. Introduced in 1848, and was based on assigning the coldest possible temperature, AKA Kelvin Zero (or absolute zero). Absolute Zero is the complete absence of all heat (no particle/molecule movement)
  10. 18. Inferring temperature visually or using touch
  11. 19. A unit of temperature commonly used in Canada
  12. 21. Energy from moving air
  13. 24. Gasses prevent thermal energy from escaping into space
  14. 26. Energy from extremely hot materials from inside the Earth (volcanoes, geysers, and hot springs)
  15. 27. The transfer of thermal energy through currents in fluids
  16. 28. all systems transfer some of their energy as heat into their surroundings
  17. 33. Amount of thermal energy it takes to warm or cool the object by one degree celsius.
  18. 34. The state of matter where the substance does not have a definite shape nor volume.
  19. 35. Energy is from solar energy heating the air
  20. 37. Devices: Devices that have digital components and sensors, and use electricity.
  21. 38. the measurement of something’s ability to do things (the ability to do change). Energy has no matter or shape.
