Question

The room-temperature tensile strengths of pure lead and pure tin are 16.8 MPa and 14.5 MPa, respectively.

a) Pure lead
b) Pure tin
c) Both are equal
d) Cannot be determined

Answer 1

Pure lead has a higher room-temperature tensile strength (16.8 MPa) compared to pure tin (14.5 MPa), which makes it the correct answer to the question regarding which material has greater tensile strength.

Step-by-step explanation:

The question pertains to the room-temperature tensile strengths of pure lead and pure tin, which are 16.8 MPa and 14.5 MPa, respectively. Based on these values, it is clear that pure lead has a higher tensile strength than pure tin at room temperature. Therefore, the correct option would be:

• Pure lead

It is important to understand that tensile strength is a material's resistance to breaking under tension. The higher the tensile strength, the less likely the material is to stretch or break under tension. Lead and tin are both relatively soft metals with low tensile strengths compared to other metals, but even among soft metals, there can be significant differences in mechanical properties, such as tensile strength.
