  1. 3. Matter with constant composition. All particles have the same properties.
  2. 4. a process that absorbs energy from the surroundings.
  3. 5. during a chemical change, the composition of matter always changes, atoms are rearranged, but the same number and type of atoms remains the same.
  4. 6. A mixture made up of particles that are uniformly distributed.
  5. 8. A substance made up of atoms with the same atomic number.
  6. 11. A pure substance is matter that has a definite composition.
  7. 13. A mixture made up of particles that are not uniformly distributed.
  8. 14. is the energy possessed by an object due to its position,composition or condition.
  9. 15. Energy in motion
Down
  1. 1. Mass cannot be destroyed or created, It remains the same during a chemical reaction.
  2. 2. particles of matter are always in motion,The kinetic energy of the particles increases as temperature increases.
  3. 7. Matter with variable composition, made from two or more substances.
  4. 9. process that releases energy into the surroundings.
  5. 10. Anything that has both mass and volume.
  6. 12. A substance made from two or more elements, chemically combined.
