The autoignition temperature of hydrogen is approximately 500°C (932°F) in air. This is the temperature at which hydrogen gas will spontaneously ignite without the need for an external ignition source.
The flash point of hydrogen peroxide is around 186 degrees Celsius (367 degrees Fahrenheit). This is the temperature at which the vapors from the substance can ignite momentarily in the presence of a flame.
Typically the lowest temperature that gasoline will produce enough vapors to ignite at is -40 degrees Fahrenheit.
Hydrogen bromide is a colorless gas at standard temperature and pressure.
Hydrogen gas is stable under certain conditions but can be reactive under others. It is flammable and can ignite in the presence of oxygen. In its elemental form, hydrogen is colorless, odorless, and tasteless.
The autoignition temperature of hydrogen is approximately 500°C (932°F) in air. This is the temperature at which hydrogen gas will spontaneously ignite without the need for an external ignition source.
The flash point of hydrogen peroxide is around 186 degrees Celsius (367 degrees Fahrenheit). This is the temperature at which the vapors from the substance can ignite momentarily in the presence of a flame.
It is enough for a spark to ignite any fuel.
I think you mean oxygen. However, hydrogen itself might ignite if heated enough by the splint. The chemical property is, anyway, either carbon or hydrogen's affinity with oxygen.
Ammonia does not ignite easily at normal temperatures. To ignite ammonia gas, you typically need a temperature of around 651 degrees Celsius (1204 degrees Fahrenheit).
Natural gas ignites at a temperature of around 1,076 degrees Fahrenheit.
Coal will ignite and start to burn at a temperature of around 700-800 degrees Celsius (1292-1472 degrees Fahrenheit).
Typically the lowest temperature that gasoline will produce enough vapors to ignite at is -40 degrees Fahrenheit.
The minimum temperature required for fire to ignite is typically around 600 degrees Celsius (1,112 degrees Fahrenheit).
The temperature at which point a flammable can ignite.
The air temperature in a diesel engine cylinder is 1022 F. This will ignite the fuel. the high compression, 22 to1, will light the fuel. A spark engine with a carburetor may "diesel" when the key is turned off because of glowing carbon deposits in the cylinder, self ignition.
Auto-ignite refers to the spontaneous ignition of a substance without an external ignition source, typically due to high temperature or pressure. It occurs when the substance reaches its auto-ignition temperature or pressure and ignites without the need for a spark or flame.
