Which of the following statements about steel is false?
A)It contains carbon atoms in the holes of its iron crystals.
B)The presence of carbon-iron bonds in the alloy make steel harder and stronger than pure iron.
C)Pure iron is relatively soft and ductile because it lacks directional bonding.
D)The amount of carbon directly affects the properties of steel.
E)All of these are true.

Question

Quizplus · Accepted Answer

All the statements provided about steel are true. Steel indeed contains carbon atoms in the holes of its iron crystals, which contributes to its hardness and strength compared to pure iron. The presence of carbon-iron bonds does make steel harder and stronger. Pure iron's softness and ductility are due to its lack of directional bonding, and the amount of carbon in steel directly affects its properties, such as hardness, ductility, and tensile strength.
