Describe how the liquid petroleum pipeline can carry different products?
By using PIGs (plug-like devices) that isolate the different materials allowing multiple products
to exist in the same pipeline.
Biological agents and toxins
Generally no lethal but could cause asphyxiation
Concentration
Amount of acid or base compared to the amount of water present
Endothermic
Absorbs heat
exothermic
Release of heat
Inhibitor
A substance that slows down or stops a chemical reaction
