Q: What happens if a vapor has a density value LESS than 1?
Answer:
The vapor is lighter than air and will rise.
(Ex. Hydrogen Gas)
Q: What happens if the vapor has a density value EQUAL to 1?
Answer:
The vapor is the same weight as air and would mix with the air easily.
(Ex. Carbon Monoxide)
Q: Why is in helpful for firefighters to have a good understanding of a substance’s vapor
density?
Answer:
They may be able to predict the spread or migration of the vapors and possibly remove any
ignition sources that may be in the vapor’s path.
Q: The ratio of the density of a liquid or solid, as compared to the density of an equal volume of
water, with water having an assigned value of 1 is called?
Answer:
Specific Gravity<\/p>\n\n\n\n
Q: What happens when a liquid or solid has a Specific Gravity higher than 1?
Answer:
The liquid or solid is heavier than the water and will sink.
(Ex. Carbon Disulfide)
Q: What happens when a liquid or solid has a Specific Gravity lower than 1?
Answer:
The liquid or solid is lighter than the water and will float.
(Ex. Gasoline, Kerosene, and Wood)
Q: What is the danger of using water on a flammable liquid with a low specific gravity?
Answer:
The water may actually spread the liquid and the fire rather than putting the fire out.
Q: The degree of rapidity with which a substance evaporates to a gaseous state is called?
Answer:
Volatility
Q: The lowest temperature at which a substance begins to release ignitable vapors sufficiently
fast enough to “flash” when exposed to an outside ignition source but DOES NOT CONTINUE
TO BURN is called?
Answer:
