Document Summary
Chapter 4 - properties of matter and the analysis of glass. The forensic scientist must constantly determine those properties that impart distinguishing characteristics to matter, giving it a unique identity. Physical properties such as weight, volume, color, boiling point, and melting point describe a substance without reference to any other substance. A chemical property describes the behavior of a substance when it reacts or combines with another substance. Scientists throughout the world use the metric system of measurement. The metric system has basic units of measurement for length, mass, and volume; they are the meter, gram, and liter, respectively. The following are common prefixes used in the metric system: deci, centi, milli, micro, nano, kilo, and mega. An element is the simplest substance known and provides the building block from which all matter is composed. Matter is anything that has a mass and occupies space. All of the elements are listed by name and symbol in the periodic table.
