In this activity, we explore
In this activity, we explore the behaviour of different carbon compounds on burning. First we burn a few camphor tablets and see that it produces a bright yellow flame whose soot can be easily collected by holding a spoon over the flame. Then we burn a small amount of ethanol and see that it produces a yellow-blue flame which is hotter but less bright. In this case we cant collect any soot on a spoon by holding it over a flame. The difference is due to the number of carbon atoms in each compound. Ethanol only has 2 carbon atoms and can easily produce carbon dioxide while camphor has 10 carbon atoms and all of them are cannot produce carbon dioxide. Therefore we get soot with camphor which has a higher number of carbon atoms. The separation of crude oil into different fuels like petrol, diesel, etc depends on how many carbon atoms are there in the different fuels.
