[amp_mcq option1=”By heating wood at high temperature in absence of air” option2=”By heating coal at high temperature in absence of air” option3=”By burning hydrocarbons in a limited supply of air” option4=”By heating coal at high temperature in presence of air” correct=”option2″]<\/p>\n
The correct answer is: B. By heating coal at high temperature in absence of air<\/strong>.<\/p>\n Carbon black is a fine black powder that is produced by incomplete combustion of organic materials, such as coal, petroleum, or natural gas. It is used in a variety of applications, including tires, plastics, inks, and paints.<\/p>\n The process of producing carbon black is called carbonization. It involves heating coal at high temperatures in the absence of air. This causes the coal to break down into its component elements, including carbon. The carbon is then collected and processed into a fine powder.<\/p>\n Carbon black is a valuable material with a wide range of applications. It is used to improve the strength, durability, and appearance of a variety of products. It is also used to absorb ultraviolet light and to protect against the sun’s harmful rays.<\/p>\n Here is a brief explanation of each option:<\/p>\n [amp_mcq option1=”By heating wood at high temperature in absence of air” option2=”By heating coal at high temperature in absence of air” option3=”By burning hydrocarbons in a limited supply of air” option4=”By heating coal at high temperature in presence of air” correct=”option2″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[636],"tags":[],"class_list":["post-5095","post","type-post","status-publish","format-standard","hentry","category-non-metal-and-its-compounds","no-featured-image-padding"],"yoast_head":"\n\n
