Question: What happens to the Young\'s modulus of a material when it is heated?
Options:
It increases
It decreases
It remains constant
It becomes zero
Correct Answer: It decreases
Solution:
Generally, the Young\'s modulus of a material decreases when it is heated due to increased atomic vibrations.

Questions & Step-by-Step Solutions
What happens to the Young's modulus of a material when it is heated?
Correct Answer: Young's modulus decreases
Step 1: Understand what Young's modulus is. It is a measure of how stiff a material is.
Step 2: Know that when a material is heated, its temperature increases.
Step 3: Realize that heating a material causes its atoms to vibrate more.
Step 4: Understand that increased atomic vibrations make it easier for the material to deform.
Step 5: Conclude that because the material can deform more easily when heated, its Young's modulus decreases.
Young's Modulus – Young's modulus is a measure of the stiffness of a material, defined as the ratio of stress to strain in the linear elastic region of the material.
Effect of Temperature – Heating a material increases atomic vibrations, which generally leads to a decrease in Young's modulus as the material becomes less stiff.
