Q
Q: What happens to the Young's modulus of a material when it is heated?
Solution:
Generally, the Young's modulus of a material decreases when it is heated due to increased atomic vibrations.
Steps: 5
Show Steps
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.
