Across
  1. 3. A form of energy transferred between systems due to a temperature difference.
  2. 4. Energy
 Energy derived from the heat stored beneath the Earth's surface.
  3. 7. Fuels
 Natural energy sources like coal, oil, and natural gas, formed from ancient biological matter.
  4. 8. Energy
 Energy derived from natural sources that are replenished over time (e.g., solar, wind).
  5. 11. Power
 Electricity generated from the movement of water, typically via dams or water wheels.
  6. 12. The ratio of useful energy output to total energy input, indicating how well energy is utilized.
  7. 14. Energy
 Energy from sources that are finite and will eventually be depleted (e.g., coal, oil, natural gas).
  8. 15. A measure of disorder or randomness in a system, often related to energy dispersal.
  9. 18. Energy
 Energy stored in the bonds of atoms and molecules, released in chemical reactions.
  10. 19. Energy
 Energy harnessed from the sun, often through photovoltaic cells or solar thermal systems.
  11. 20. Energy
 Energy stored in the nucleus of an atom, released through nuclear reactions.
Down
  1. 1. The rate at which energy is transferred or converted.
  2. 2. Energy
 The sum of kinetic and potential energy in a system.
  3. 5. Transfer of energy when a force is applied to an object causing displacement.
  4. 6. Energy
 Energy of motion, associated with any object in movement.
  5. 9. Transfer
 The movement of energy from one place or form to another (e.g., mechanical to thermal energy).
  6. 10. Conservation
 Reducing energy use by improving efficiency and adopting sustainable practices.
  7. 13. Energy
 Energy associated with the flow of electric charge (current).
  8. 16. Energy
 Stored energy, often due to an object's position or state.
  9. 17. Energy
 Energy related to the temperature of a system, often due to molecular motion.
