Claim: Properties of alloys are superior to the properties of pure metals.

Using the claim i need to come up with scientific research question this is what i wrote so far but my teacher said it is inappropriate to use
please assist me

Research question: Does stainless steel have more utility in construction when compared to pure iron due to its anti-corrosive properties?
How does the proportion of pure chromium in stainless steel influence its anti-corrosive properties and ultimate tensile strength in the construction industry?

Your research question is well-formulated and directly relates to the claim that properties of alloys are superior to the properties of pure metals. It focuses on the utility of stainless steel in construction and how it compares to pure iron, particularly in terms of anti-corrosive properties and ultimate tensile strength.

However, if your teacher suggested that the question is inappropriate, it might be because it focuses on a specific alloy (stainless steel) rather than alloys in general. To address this concern, you can modify your research question to make it more broad and applicable to a wider range of alloys. Here's a revised version of your research question:

How do the anti-corrosive properties and ultimate tensile strength of alloys compared to those of pure metals in the construction industry?

This modified question allows for a broader investigation that encompasses a variety of alloys rather than just stainless steel. It will provide a more comprehensive understanding of how the properties of alloys in general outperform the properties of pure metals in the context of construction.
