- Cracking (I) is a process in the Petroleum (B) industry used to break down large hydrocarbon molecules into smaller, more useful ones like gasoline. - Smelting (II) is a process of applying heat to ore in order to extract a base metal, commonly used in the Copper (C) industry. - Hydrogenation (III) is the addition of hydrogen to a substance. It is used in the Edible fats (D) industry to convert liquid vegetable oils into solid or semi- solid fats like margarine. - Vulcanization (IV) is a chemical process for converting natural rubber or related polymers into more durable materials by adding sulfur or other equivalent curatives, associated with the Rubber (A) industry.
