The ignition temperature of kerosene (#1 fuel oil) is 490 degrees fahrenheit (254C), the same as all fuel oils.
kerosene
kerosene has got higher ignition temperature.
LPG (liquefied petroleum gas) has a lower ignition temperature compared to kerosene. This means that LPG ignites at a lower temperature than kerosene, making it more flammable and easier to ignite.
The auto-ignition temperature of kerosene is typically in the range of 210-300 degrees Celsius (410-572 degrees Fahrenheit), depending on the specific composition and purity of the kerosene.
At approx. -45 0C, depending on the specific composition of a given kerosene.
200 degrees C
The specific gravity of kerosene typically ranges from 0.78 to 0.82, depending on the type and temperature of the kerosene. This value indicates that kerosene is less dense than water, as water has a specific gravity of 1.
Petrol is more flammable than kerosene because petrol has a lower flash point and autoignition temperature. This means petrol is more likely to ignite at lower temperatures compared to kerosene.
The refractive index of kerosene at 20°C is approximately 1.448.
The evaporation rate of kerosene depends on factors such as temperature, surface area exposed, and air circulation. At room temperature, it typically takes a few hours to a day for a cup of kerosene to fully evaporate. It's important to note that kerosene is flammable, so proper ventilation and safety precautions should be taken when allowing it to evaporate.
If ice cubes are put in kerosene, the ice will melt due to the higher temperature of the kerosene. Kerosene has a lower freezing point than water, so it will not freeze the water in the ice cubes. The ice will eventually melt and mix with the kerosene, but they will not chemically react with each other.
The refractive index of kerosene varies with its composition, but typically ranges between 1.43 to 1.47 at room temperature. This means that light travels through kerosene at a speed 1.43 to 1.47 times slower than in a vacuum.
