REVIEW – Chapter 4 – Forensic Examination of Glass

 

  1. A(n) _____________________ property describes the behavior of a substance without reference to any other substance.
  2. A(n) _____________________ property describes the behavior of a substance when it reacts or combines with another substance.
  3. The _______________ system of measurement was devised by the French Academy of Science in 1791.
  4. The amount of matter an object contains determines its _________________.
  5. Mass per unit volume defines the property of ______________________.
  6. If an object is immersed in a liquid of greater density, it will (sink, float).
  7. The bending of a light wave because of a change in velocity is called __________________________.
  8. The physical property of ______________ is determined by the ratio of the velocity of light in a vacuum to light’s velocity in a substance.
  9. Glass that can be physically pieced together has _____________________ characteristics.
  10. The two most useful physical properties of glass for forensic comparisons are _____________________ and ______________________.
  11. Comparing the relative densities of glass fragments is readily accomplished by a method known as _________________________.
  12. When glass is immersed in a liquid of similar refractive index, its _____________ disappears and minimum contrast between the glass and liquid is observed.
  13. The fracture lines radiating outward from a crack in glass are known as _________________ fractures.
  14. A crater-shaped hole in glass is (narrower, wider) on the side where the projectile entered the glass.
  15. True or False – It is easy to determine from the size and shape of a hole in glass whether it was made by a bullet or some other projectile. _________________
  16. True or False – Stress marks on the edge of a radial crack are always perpendicular to the edge of the surface on which the impact force originated. ____________
  17. A fracture line (will, will not) terminate at an existing line fracture.
