Thermal Expansion - Atomic

Question 1

What is the Symmetry of E(r)

Answer 1

Asymmetric

Question 2

IF E(r) is asymmetric it means that:
* Median _ is middle of gap height at _
* r ______ with T

Answer 2

IF E(r) is asymmetric it means that:
* Median r (interatomic spacing) is middle of gap height at E (energy lines)
* r Increases with T ( r ∝ T)

Question 3

What would happen is E(r) was symmetric? **

Answer 3

• Thermal Expansion Coefficient = 1**
• Thermal Expansion is usually close to 0 **
