Why does a flammable material such as gasoline need a spark to ignite?
Flammable materials like gasoline require a spark to ignite because combustion needs three elements: fuel, heat, and an oxidizer (usually oxygen in the air). Gasoline vapor must first mix with air to form a combustible mixture, and the spark provides the necessary heat to raise the temperature of this mixture to its ignition point. Without that initial heat source, the gasoline will not reach the temperature required for self-sustained combustion.
Is diesel flammable?
Actually, Diesel is not flammable, it is combustible. The difference is the flash point. Diesel does not flash until 143 degrees Fahrenheit. Anything between 100 and 200 is combustible; less than 100 is flammable. Compare it to "gasoline" which has a flash point of -42 F (I think).
Why does petrol catches fire easily?
Petrol catches fire easily because it is a highly flammable liquid that evaporates quickly at room temperature, creating a mixture of vapor and air that is easily ignitable. Additionally, petrol has a low flash point, which is the temperature at which it can produce enough vapor to ignite when exposed to a flame. These factors make petrol highly flammable and pose a fire risk.
Are the products or reactants more dangorious in burning gasoline?
The reactants (gasoline vapors) are more dangerous in a gasoline fire, as they are highly flammable and can ignite easily. The products of combustion (carbon dioxide, water vapor, carbon monoxide) are a byproduct of the burning process and are less hazardous in terms of fire risk.
How do you measure flashpoint of gasoline?
The flashpoint of gasoline can be measured using a closed-cup tester designed to determine the lowest temperature at which the gasoline vapor can ignite when exposed to an ignition source under specific conditions. This is an important safety parameter to assess the flammability risk of a substance.
What are flammable materials.?
what is a flashpoint <><><> The temperature at which a substance gives off an ignitable vapor is the flash point. If the flash point is under 100 degrees F, it is a flammable (gasoline). If it is over 100, it is a combustible (diesel fuel). Flash point is NOT the ignition temperature.

How many cubic feet of fuel vapor do you get when you boil 1 gallon of gasoline?
There is no definite answer unless you designate the temperature and of the gasoline since gas expands as temperature increases. I just don't want to be around when you are boiling gasoline.
Is gasoline a liquid or a vapor form?
Gasoline is a liquid, gas is a vapor.
How much vapour is generated from 1 liter gasoline at 35 deg C?
The amount of vapor generated from 1 liter of gasoline at 35°C can vary based on the specific composition of the gasoline, but on average, gasoline has a vapor pressure of about 40-50 kPa at this temperature. Generally, approximately 150 to 200 milliliters of vapor can be generated from 1 liter of gasoline under these conditions. However, these values can fluctuate based on factors like the exact formulation of the gasoline and ambient pressure.
Is diesel flammable?
Actually, Diesel is not flammable, it is combustible. The difference is the flash point. Diesel does not flash until 143 degrees Fahrenheit. Anything between 100 and 200 is combustible; less than 100 is flammable. Compare it to "gasoline" which has a flash point of -42 F (I think).
How many cu ft of vapor in 1 cu ft of liquid gasoline?
The answer will depend on the pressure and temperature.

What is the Reid vapour pressure of gasoline?
Reid vapor pressure (RVP) of gasoline is the vapor pressure at 100°F.
How much does a gallon of gasoline vapor weigh?
Briefly, the saturated vapor volume of an average gallon of liquid gasoline when fully evaporated is 160.4 gallons of vapor at 60° F and sea level.Vapor volume of a liquid is the number of cubic feet of vapor resulting from the complete evaporation of the liquid. The vapor volume depends on parameters of density, temperature, pressure and molecular weight which is affected by the variety of formulas for gasoline that is comprised of a wide range of hydrocarbons.Several approaches are available to solve this problem. One is shown below.Using a common industrial formula:one liquid gallon = [(8.31) x (SG) x (387 cu ft)] / (MW)Where:8.31 = pounds in gallon of waterSG = specific gravity of liquid being vaporized387 = At standard conditions, one pound-molecular weight of a material will evaporate to fill 387 cubic feet of space.MW= molecular weight of liquid being vaporizedThen using the approximate gasoline constants:one liquid gallon of gasoline = [(8.31 pounds in a gallon of water) x (.70 approx. specific gravity of gasoline) x (387 cu ft)] / (105 molecular weight of average gasoline)= 21.4 cubic feet of vapor volumeThere is 7.481 U.S. gallons in one cubic foot.So:one liquid gallon of gasoline = (21.4 cubic feet) x (7.481)= 160.4 gallons of saturated gasoline vaporThe vapor volume will vary based on the specific formulation of gasoline, pressure, and temperature.D.

What has to happen for a gas or vapor to be flammable or an explosion hazard?
For a gas or vapor to be flammable or an explosion hazard it must have a concentration in air between the Lower Explosive Limit (LEL) and the Upper Explosive Limit (UEL) for that particular gas or vapor.
What is the source of gasoline that cars run on?
The source is Crude oil. Gasoline is extracted by heating cude oil and collecting the vapor at a specific temperature. The condensate is gasoline. The process is known as 'Cracking' and may have other chemicals added, to make the process more efficient.
