The flash point of diesel is typically around 52-96°C (126-205°F), while kerosene has a flash point of around 37-65°C (100-150°F). The fire point for diesel is usually higher than its flash point, around 52-96°C (126-205°F), while for kerosene, it is around 46-74°C (115-165°F).
The flash point difference between diesel and gasoline is that diesel has a higher flash point than gasoline. Diesel typically has a flash point of around 125-180 degrees Celsius, while gasoline has a flash point of around -40 to -60 degrees Celsius.
petrol has a lower flash point and is more volatile than diesel.
The flash point of petrol represents the temperature at which it can ignite when exposed to an open flame. However, for petrol to combust, it must also be in the presence of oxygen and have an ignition source. In summer, the atmosphere temperature being higher than the flash point of petrol alone is not sufficient to cause it to catch fire without these additional factors.
Ignition temperature is the minimum temperature at which a substance will ignite and sustain combustion, while flash point is the temperature at which a substance will produce enough vapor to ignite in the presence of an ignition source. Ignition temperature is higher than flash point. Knowing these values helps determine the potential fire hazard of a substance and allows for proper safety measures to be implemented to prevent fires and explosions.
A flammable material has a lower flash point (100F or below) while a combustible material has a flash point of 100F or HIGHER. In other words, it's a lot easier for a flammable material to catch fire than a combustible one because of the minimal amount of energy (heat) required to get it going versus the higher requirement of a combustible material.
to this day diesel is the "best" to burn it has a higher flash point than gasoline so it burns hotter and better
The boiling point is always higher than the melting point.
In common usage flammable liquids are the same as combustible liquids in terms of their ability to catch fire. However, in the technical usage of hazardous materials transportation and of fire prevention, a combustible liquid has a higher flash point than a flammable liquid and is therefore less easily ignited. So, yes, flammable liquids ignite more easily than do combustible liquids.

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).
Flammability refers to how easily a substance can catch fire or ignite when exposed to heat, sparks, or flames. It is an important safety consideration in handling and storing chemicals, with flammable substances posing a higher fire risk than non-flammable ones. Flammability is typically indicated by a material's flash point, autoignition temperature, and flammable range.
