Across
  1. 3. The smallest unit of matter of a substance that retains all the physical and chemical properties of that substance: consists of a single atom or a group of atoms bonded together
  2. 4. A property of mineral that describes how easily it can be scratched.
  3. 6. anything that takes up space and has mass
  4. 10. A force that opposes motion through direct contact
  5. 11. The maximum absolute variation of any periodic function (e.g., a wave).
  6. 13. To transmit heat, sound, or electricity through a medium
  7. 15. The process by which water is changed from a gas (water vapor) to a liquid; a stage of the water cycle.
  8. 16. The change in direction of a wave caused by passing by an obstacle or traveling through an opening
  9. 21. The rate at which velocity is changing. The change may involve an increase or decrease in speed and/or a change in direction. The change may be positive or negative
  10. 23. A type of mixture in which different parts can be easily distinguished.
Down
  1. 1. A type of mixture in which the different parts are blended evenly so that the mixture is the game throughout
  2. 2. Heat transfer in a gas or liquid by the circulation of currents from one region to another
  3. 5. The process by which water changes from a liquid to a gas (water vapor); a stage of the water cycle.
  4. 7. A term used to describe the electric or magnetic force exerted by oppositely charged objects or to describe the gravitational force that pulls objects toward each other.
  5. 8. Unit of energy, the amount of heat needed to raise one gram of water one degree Celsius at standard atmospheric pressure
  6. 9. A material used to reduce or prevent the transfer of electricity, heat, or sound.
  7. 11. To take up and store energy without reflecting or transmitting that energy
  8. 12. A push or a pull that one object exerts on another object with or without direct contact (e.g. frictions gravity)
  9. 14. A stable elementary particle that is negatively charged and orbits the nucleus of an atom.
  10. 17. The property of an object, due to its mass, by which it resists any change in its position unless overcome by force.
  11. 18. The peak or highest point on a wave
  12. 19. The amount of matter substance or object has
  13. 20. The number of cycles or waves per unit time
  14. 22. A property of a mineral that describes how it appears when it reflects light
