Question
Match the alloy names listed in Group I with the main elements present in them listed in Group II. Group I Group II P. Babbit 1. Fe-Ni Q. Muntz metal 2. Ni-Cr-Fe R. Invar 3. Cu-Zn S. Inconel 4. Sn-Sb-Cu
The correct answer is
P-4, Q-3, R-1, S-2
Alloy Composition Identification
This section explains the primary elements present in the alloys listed in Group I to match them correctly with Group II.
Alloy Element Analysis:
- P. Babbit: This is a bearing alloy typically composed of Tin (Sn), Antimony (Sb), and Copper (Cu). Therefore, P matches with 4. Sn-Sb-Cu.
- Q. Muntz metal: Known as a type of brass, its main constituents are Copper (Cu) and Zinc (Zn). Thus, Q matches with 3. Cu-Zn.
- R. Invar: This alloy is primarily Iron (Fe) and Nickel (Ni), famous for its minimal thermal expansion. Hence, R matches with 1. Fe-Ni.
- S. Inconel: This is a high-performance alloy based on Nickel (Ni), often including Chromium (Cr) and Iron (Fe). Therefore, S matches with 2. Ni-Cr-Fe.
Matching Result
Based on the analysis, the correct pairings are:
- P - 4
- Q - 3
- R - 1
- S - 2
This combination represents the correct matching of alloys with their primary elements.
