  1. 1. Phase change that involves the conversion from solid to
  2. 2. Group 7A elements.
  3. 3. mass: Indicates that one mole of an element has a mass in grams numerically equal to its atomic mass units
  4. 5. the size: length: or amount of something: as established by measuring.
  5. 6. mass:The quantity of matter in the body mass.
  6. 7. the closeness of a single measurement to its true value.
  7. 9. the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they
  8. 12. Positively:charged subatomic particle of an atom significant figures: The digits in any measurement that are known with certainty plus one digit which is uncertain
  9. 13. Ratio of the mass of an object to the volume occupied by that object.
  10. 14. it is a branch of chemistry that studies the chemical processes within and relating to living organisms. Biochemical processes give rise to the complexity of life.
