Question
What are steels and what elements do they typically contain?
Answer
Steels are alloys of iron that typically contain carbon and sometimes other metals. The addition of carbon increases the strength and hardness of the iron.
Explanation
This question tests the student's recall of the composition of steels as specified in the learning objective. It assesses their understanding of what constitutes an alloy and the specific elements involved.
Common mistake
Misunderstanding Steel Composition
Students often think that all steels contain the same amount of carbon and that they are only made from iron.
Remember that steels are alloys of iron that can contain varying amounts of carbon and sometimes other metals, leading to different properties.
