Lead is more ductile than iron. The correct option is A. Lead is more ductile than iron
<h3>Young's modulus </h3>From the question, we are to determine the statement which is true
First, we will define the term <em>Young's modulus </em>
<em>Young's modulus</em> is a measure of the stiffness of an elastic material. It is also given as the ratio of <u>stress </u>to <u>strain</u>. That is,
The greater the modulus, the stiffer the material.
Materials with low Young's modulus tend to be <u>ductile </u>and materials with high Young's modulus tend to be <u>brittle</u>
Since the Young's modulus value for iron is higher than that of lead, then iron is <em>stiffer </em>than lead.
Thus, lead is more ductile than iron. The correct option is A. Lead is more ductile than iron
