Gasoline does not ignite. The fumes from gasoline are what ignites. They will ignite at any temperature.

According to the best sources I could find there are three answers (all apply to gas fumes as stated above).

1.) Flash point -43 F

2.) Ignition Temp -40

both of the above require an external source of ignition. Then .....

3.) Auto Ignition Temp 246--280 °C (475--536 °F)

Is the answer for what temp it will ignite on it's own without external 'spark'.

I leaned heavily on Wikipedia for source material

What is occurring when a piece of potassium metal ignites in a beaker of water?

The potassium reacts with water to produce potassium hydroxide, hydrogen gas, and large amounts of heat. The heat ignites the hydrogen which in turn ignites the potassium.


Is gasoline not flammable?

Gasoline is indeed flammable. It is a volatile liquid that easily ignites and burns when exposed to a spark, flame, or heat source. This is why it is a common fuel for vehicles and other machinery that rely on internal combustion engines.


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.


Why does a diesel engine use a different type of fuel?

Diesel engines do not require "ignition" to burn diesel fuel--it is powered by the "heat of compression" therefore diesel fuel has a much higher "flash point" than gasoline. If you were to put gasoline in a diesel engine you would probably blow the heads off the engine. Due to lower "flash point" (temperature when fuel ignites). If you were to put diesel fuel in a gasoline powered engine, it would not ignite and engine will not start. Due to higher "flash point).


Why the temperature of water the same as room temperature before heating?

The temp is the heat so it can't be hotter than the heat :)


Why is oxygen needed by rockets and how does it get it?

The first part is simple, you need three things for a fire: Heat fuel Oxygen You get liquid oxygen that is mixed in with the just fuel before it ignites.


What is the average heat for wood?

Not sure of your question- if you mean what is the heat produced by burning wood, it varies with the type of wood. See the link at the bottom of the page for more information on heat value of wood. If you mean the temperature at which wood ignites- again, that varies, but between 455 and 500 degrees F.


What is the meaning of pre-heat?

Pre-heat means to heat an oven or appliance to a desired temperature before using it for cooking or baking. This allows the appliance to reach the necessary temperature for the food to cook evenly and properly.


Why cant a rock catch on fire?

No Fuel. To make a fire, you need three things. Air, Fuel, Heat. Air is all around you. Fuel can be many things, heat can be friction, spark, lightning, flame. It is the same inside a car engine. Air is sucked into the cylinders, gasoline vaper is mixed, and the sparkplug ignites the mixture.


What provides ignition for an oil burner?

An oil burner typically ignites using an electric igniter or a spark igniter. The igniter generates a spark or heat that ignites the oil to initiate combustion.


What are the steps of a forest fire?

Fuel accumulates.Source of heat ignites fire.Fire burns until fuel is gone or there is not enough heat to continue.Fire goes out.


Is gasoline thermal energy?

Yes, gasoline is a form of thermal energy because it can be burned to produce heat. When gasoline is combusted in an engine, the heat energy is converted into mechanical energy to power the vehicle.
