Is kerosene highly flammable?
However, when compared with other substances such as petrol, kerosene is less volatile. Petrol is so volatile that it will give off enough flammable vapours at -43 °C to ignite in the presence of an ignition source. Therefore, kerosene is very flammable, but it is less volatile and safer to use than petrol.
What is the flash point of gasoline?
Flash point of gasoline. Now about the flash point: gasoline placed in an open bin has a flammable vapour above the surface when temperature of the liquid is – 23 °C. You can imagine a cloud of gasoline vapour hanging above the surface of the liquid. When a spark or flame hits the vapour, it ignites. A low flash point is more dangerous.
What happens when you put a burning match in a gasoline saucer?
At standard indoor temperature we try to light both liquids with a burning match. As the flash point of gasoline is -23 ̊C, the gasoline instantly catches fire. Initially nothing happens to the diesel when we put our burning match in the liquid. Why? The temperature of the diesel needs to be heated up to 55 ̊C degrees by the match before the liquid starts burning. The tip of the burning match touching the liquid is about 1000 ̊C. It takes over a full minute before the diesel starts burning.
What is spontaneous ignition?

As the air compresses, it begins to heat up and reaches a temperature that ignites the fuel.
What is a closed cup test?
There are two types of closed cup testers: non-equilibrial, such as Pensky-Martens, where the vapours above the liquid are not in temperature equilibrium with the liquid, and equilibrial , such as Small Scale (commonly known as Setaflash), where the vapours are deemed to be in temperature equilibrium with the liquid. In both these types, the cups are sealed with a lid through which the ignition source can be introduced. Closed cup testers normally give lower values for the flash point than open cup (typically 5–10 °C or 9–18 °F lower) and are a better approximation to the temperature at which the vapour pressure reaches the lower flammable limit. In addition to the Penskey-Martens flash point testers, other non-equilibrial testers include TAG and Abel, both of which are capable of cooling the sample below ambient for low flash point materials. The TAG flashpoint tester adheres to ASTM D56 and has no stirrer, while the Abel flash point testers adheres to IP 170 and ISO 13736 and has a stirring motor so the sample is stirred during testing.
