Question

The process of making steel developed by Henry Bessemer a. All these answers are correct. b. included both blowing air through and adding ingredients to molten iron. c. was also developed by an American, William Kelly. d. included blowing air through molten iron. e. involved adding ingredients to molten iron.

Answer 1

The Bessemer process of making steel involved blowing air through molten iron and adding certain ingredients, and was also developed by William Kelly. It was critical to industrial advancements, leading to mass production of steel and enabling major engineering feats.

Step-by-step explanation:

The process of making steel developed by Henry Bessemer included blowing air through molten iron and adding ingredients to it. This method was crucial in industrial advancements and played a significant role in the mass production of steel. Henry Bessemer's invention, known as the Bessemer process, along with the open-hearth process, revolutionized steel production in the United States and ushered in a new industrialized age, leading to monumental engineering achievements such as skyscrapers and the expansion of railroads. The Bessemer process was also developed independently by an American named William Kelly at around the same time as Bessemer. Interestingly, the steel magnate Andrew Carnegie later utilized the Bessemer process to dominate the steel industry in the United States, making better steel at lower prices than his competitors by controlling the entire production process.

Answer 2

The correct option is: a. All these answers are correct

Step-by-step explanation:

The Bessemer process was the first industrial steel-making process by using pig iron in its molten state developed by English inventor, Sir Henry Bessemer in 1856.

In this method, air is blown through the molten iron to remove the impurities present by oxidation, which increases the temperature of the molten iron. After the removal of impurities, certain additives are also added to it.

A similar method was also developed by the American inventor, William Kelly in the year 1851.

Therefore, all the given options are correct.
