QUESTION 7
The progress of man to higher standards of living are enabled by his capacity to maximize the utility of the properties of materials for a specific purpose through intelligent design and materials engineering. In the stone age, shards of flint served as cutting instruments and arrow tips. Bronze replaced flint when man learned to alloy copper and tin.The use of iron and then steel had to wait until man could achieve the 1000 DegF higher processing temperature required to melt iron instead of bronze.

Indicate the order in which the following advances occurred

Gasoline, Pure Silicon Crystal, Gunpowder, Integrated Circuit, Rockets, Internal Combustion Engine, Chain Mail, Cannons,

Answer 1

order in which advances occure

Chain mail (this is used as battle field armure in iron age , human wear it to protect themselve) , Gun powder ( mostly made of sulfur), Cannon( in this gun powder is being used),Gasoline( distillation product from crude oil), Internal combustion engine(gasoline is used in this) ,Pure silicon crystal( made after refining silica) , integrated circuit ( Pure silicon is used in integrated circuit as semiconductor) , rocket ( integrated circuit is part of rocket)
