The measure of thickness of a liquid, determines how easily it flows. During an incident, this will affect the flow away from a leaking container, expanding the endangered area.
- A.
Volatility
- B.
Viscosity
- C.
Slurry
- D.
Specific Gravity
Correct Answer
B. ViscosityExplanation
Viscosity refers to the measure of a liquid's resistance to flow. A liquid with high viscosity will flow slowly, while a liquid with low viscosity will flow easily. In the given context, the measure of thickness or viscosity of a liquid is important because it determines how easily the liquid will flow away from a leaking container during an incident. If the liquid has high viscosity, it will flow slowly and may not be able to quickly move away from the leaking container, resulting in an expansion of the endangered area. Therefore, viscosity is the correct answer in this case.Rate this question:

Materials that have at least one multiple bond between two carbon atoms somewhere in the molecule, which causes them to be more hazardous.
- A.
Unsaturated Hydrocarbons
- B.
Saturated Hydrocarbons
- C.
Aromatic Hydrocarbons
- D.
Riot Control Agents
Correct Answer
A. Unsaturated HydrocarbonsExplanation
Unsaturated hydrocarbons are more hazardous compared to saturated hydrocarbons, aromatic hydrocarbons, and riot control agents because they have at least one multiple bond between two carbon atoms in their molecular structure. These multiple bonds make them more reactive and prone to undergo chemical reactions, which can lead to the release of energy or formation of toxic byproducts. This increased reactivity and potential for chemical reactions make unsaturated hydrocarbons more hazardous than the other options listed.Rate this question:
