  1. 3. it is the sound quality refers to the shape of the sound waves.
  2. 5. it happens when heat moves directly from one object to another.
  3. 10. it carry energy but is massless.
  4. 11. it is the total energy of all the particles within the object.
  5. 13. it absorbs or reflect all of the light that hit it examples are wooden box or brick.
  6. 15. is the flow of thermal energy from a substance having higher temperature to another substance having lower temperature.
  7. 17. it is the reflection of the sound.
  8. 18. it is refers to the highness or lowness of notes.
  9. 20. it refers to the process of absorbing radiant energy.
  10. 21. it can be used to kill bacteria from implants.
  11. 23. it transfer heat through air and liquids.
  12. 24. it allows light to pass through completely examples are water and glass.
  13. 25. is the movement of energy through space in wave forms.
Down
  1. 1. it is the sound pressure produced by the vibrations of an object.
  2. 2. refers to the passing of light through a material.
  3. 4. is a material that blocks or slows the flow of heat is.
  4. 6. is the degree of hotness or coldness which can be measured using a thermometer.
  5. 7. it is determined by the amplitude is perceived by the ear as loudness.
  6. 8. is a material that transfer heat easily.
  7. 9. it allows some light to pass through, scatters some light, and objects appear blurry examples are frosted glass.
  8. 12. is a moving energy.
  9. 14. it is the bending of light or the change in direction as it passes from a less dense medium.
  10. 16. it is the time it takes for the sound waves to return can tell how far away the obstacle is.
  11. 19. it is the bouncing of light of an object.
  12. 22. it is used to locate hazards to navigation, search for the objects on the sea floor, and detect noise from marine objects and marine animals.
