[amp_mcq option1=”more than that in tar” option2=”less than that in tar” option3=”equal to that in tar” option4=”none of the above” correct=”option1″]<\/p>\n

The correct answer is: A. more than that in tar<\/strong>.<\/p>\n

Bitumen is a sticky, black, and highly viscous liquid or semi-solid form of petroleum. It is a mixture of hydrocarbons of various molecular weights and is found in natural deposits or can be a byproduct of petroleum refining. Tar is a thick, black, sticky liquid or semi-solid that is produced by the destructive distillation of coal, wood, or other organic materials. It is a complex mixture of hydrocarbons, oxygen, and sulfur compounds.<\/p>\n

The percentage of free carbon in bitumen is higher than that in tar. This is because bitumen is a more refined product than tar. The refining process removes some of the lighter hydrocarbons from bitumen, leaving behind a higher concentration of heavier hydrocarbons and free carbon.<\/p>\n

Free carbon is the non-hydrocarbon portion of bitumen. It is made up of carbon atoms that are not bonded to hydrogen atoms. Free carbon is responsible for the black color of bitumen and its high viscosity.<\/p>\n

The higher percentage of free carbon in bitumen gives it a number of advantages over tar. Bitumen is more durable and has a higher melting point than tar. It is also less likely to crack or oxidize. These properties make bitumen a better choice for use in roads, roofs, and other applications where durability is important.<\/p>\n","protected":false},"excerpt":{"rendered":"
