Physical properties allow for objects to be measured with color, density, and its melting point. Chemical properties are the way a substance changes, an example is combustion. Other examples are mass measurements, temperature (based upon standards, melting and boiling points of water), and light measurements.
What is density?
Density is the amount of mass per unit volume.
What is Algor Mortis, Rigor Mortis, and Livor Mortis?
The Algor Mortis is the drop in body temperature after one’s death, Rigor Mortis is the muscular rigidity without shortening, and Livor Mortis is the settling of blood.
What is dispersion and refraction?
Dispersion occurs when colors bend at different amounts when shone on an object, …show more content…
What cases mostly involve glass?
Cases that involve broken windshields, Molotov cocktails, burglary, and vandalism typically involve glass.
What is glass and what are the different types of glass?
Glass is an object created from silicon oxide and metal oxides. Float glass process uses raw materials such as soda lime, silica sand, calcium, oxide, and soda; which are weighted, mix, and melted at 1500 degrees Celsius. “Ordinary” sheet glass is created by passing the molten glass through rollers, displaying a finished look with distortions. Toughened glass is created by applying special treatment to float glass after it has been cut and finished. Laminated glass is created by sandwiching two or more sheets of glass and bonding them together.
What are the different combinations of glass?
Aluminosilicate glass has a higher percentage of aluminum, led alkali silicate has an increased amount of lead (II) oxide, container glass has an increased amount of sodium and a decreased amount of magnesium, and glass fibers are created by alumino-borosilicate.

GRIM II System assist in matching glass RI, which uses a step-heating stage and a RI liquid that varies in different temperatures.
What are the different glass fractures?
Radial fracture begins at a point and radiates outwards, the cracks are on the opposite sides. Concentric fracture begins as a projectile puts tension on the front surface of the glass, which leaves a larger hole on its exit.
What is the classification of evidence?
Class is a group of objects or persons with common characteristics in physical evidence, it assists in identifying a particular person.
How could you classify footprints?
Footprints could be classified through pictures, dental stones, and Plaster of Paris.
What are footprints and tire prints?
Footprints and tire prints are indentations into different types of soil, all using a diverse methods of treading throughout substances.
How to create a cast?
Make a dam around the footprint to hold the plaster, mi the casting together to prepare to poor it on the dam, pour the mixture carefully down the spatula, allow it to sit for at least an hour, and then comment on the characteristics.
