Question

An iron cork is fitted in a hole on the brass plate. What will be the effect on the fitting of the cork both are heated equally.

Answer 1

Explanation:

1. An iron cork is fitted in a hole on the brass plate.
2. Brass is the mixture of two metals which are copper and zinc.
3. Brass expands more than iron because brass is a mixture of metal that would expand more when heated while the iron is one metal that is harder to be able to expand.
4. If both the iron cork and the brass plate then the brass plate will expand more as compared to that of the iron cork.
5. So, the size of the hole will increase and hence the iron cork will be loosely fitted in the hole of brass plate.
