Gasoline Vs Fuel Ethanol Flashcards
What is the flash point of gasoline?
-45F
The flash point is the lowest temperature at which vapors of a volatile material will ignite when given an ignition source.
What is the auto ignition temperature range for gasoline?
530 - 853°F
The auto ignition temperature is the minimum temperature at which a material will spontaneously ignite without an external ignition source.
What is the specific gravity range of gasoline?
0.72 - 0.76
Specific gravity is the ratio of the density of a substance to the density of a reference substance, typically water.
What is the vapor density of gasoline?
3-4
Vapor density is the mass of a certain volume of vapor compared to the mass of an equal volume of air.
What is the vapor pressure range of gasoline?
8 - 15psi
Vapor pressure indicates the tendency of a substance to evaporate, with higher values indicating higher volatility.
What is the boiling point range of gasoline?
100 - 400°F
The boiling point is the temperature at which a liquid turns into vapor.
What is the flammable range of gasoline?
1.4% - 7.6%
The flammable range is the concentration of vapor in the air that can ignite and sustain combustion.
What is the smoke characteristic of gasoline?
Black
The color of smoke can indicate the type of material burning and its combustion efficiency.
What is the flash point of denatured fuel ethanol
-5 F
Denatured fuel is ethanol that has been treated to make it undrinkable.
What is the boiling point of denatured fuel ethanol?
709°F
This is the temperature at which denatured fuel transitions from liquid to gas.
What is the specific gravity of denatured fuel ethanol?
0.79
A specific gravity greater than 1 indicates the substance is denser than water.
What is the vapor pressure of denatured fuel?
~3psi
This indicates the volatility of denatured fuel and its propensity to evaporate.
What is the boiling point range of ethanol?
165 - 175°F
Ethanol has a lower boiling point compared to gasoline, making it more volatile.
What is the flammable range of ethanol?
3% - 19%
This range indicates the concentration of ethanol vapor in the air that can ignite.
What is the solubility characteristic of ethanol?
Slight
Ethanol is slightly soluble in water, indicating limited mixing ability.
What is the smoke characteristic of ethanol?
Trace
Trace smoke indicates a cleaner burn compared to gasoline.
True or False: Gasoline has a higher specific gravity than denatured fuel.
False
Gasoline has a specific gravity range of 0.72 - 0.76, while denatured fuel has a specific gravity of 0.79.
