BIOLOGICAL & CHEMICAL EVIDENCE ANALYSIS
There are many different types of evidence that can be found at a crime scene. Physical evidence can be collected at the crime scene such as a murder weapon. Chemical evidence is any residue from liquids that such as poison and drugs. Biological evidence is when hair or skin from a persons body has been transferred to a physical surface and then be collected and tested.
This evidence can be used to find out what exactly happened at the scene of the crime, the history behind the crime and who was involved and could have committed it.
Our experts test and analyse many forms of evidence, which is vital when finding out the various incidences that happened at a crime scene.
Similarities:
they both made sediment into soil
they both form the earth

differences:
physical is reliant usually on contact with atmospheric condition
chemical transforms rocks into sediments while physical only breaks it down
chemical uses chemical reactions

Atmospheric pressure decreases because air is less dense at higher altitudes. Because the atmospheric pressure is lower, the vapour pressure of the liquid needs to be lower to reach boiling point.
