Law of Conservation of Energy
In any chemical or physical change, energy is neither created nor destroyed but merely transformed from one form to another.
Law of Conservation of Mass
In any chemical or physical change, mass is neither created nor destroyed.
Law of Definite Proportion
When elements combine to form a compound, they do so in a definite proportion with constant composition
LD (Lethal Dose 50%)
The amount of a poison (or radiation) which will kill 50% of the group which has been poisoned.
Melting aka Liquefaction aka Liquification
Conversion of a solid or gas onto a liquid form.
State of matter w/ Definite volume, indefinte shape, particles are loosely packed and move by flow.
Standard unit of volume in the metric system.
The quantity of matter present in an object.
Anything that has mass and occupies space.
The disruption of a crystal lattice so that the particles move freely about and the solid becomes a liquid.
An element marked by luster, malleability, ductility, and conductivity of electricity and heat, and which will ionize positively in solution.
The standard metric unit of length.
Formaldehyde & water compound. Will dissociate to formaldehyde gas & water if exp. To heat, light & air
Minimum Lethal Dose (MLD)
The smalllest dose of a poison (or radiation) on record that produces death.
A combination of two or more substances not chemically united and not in definite proportion by mass.
Chemicals for which there may be greatly varying demands predicated upon the type of embalming, the environment and the arterail fluid to be used.
