Homework Equations
V=[itex]\frac{-A}{r}+\frac{B}{r^{10}}[/itex]
A=5*10^-30
B=8*10^-121
V=potential energy r=interatomic separation distance
Coefficient of thermal expansion = [itex]\frac{change in L}{L*change in T}[/itex]
The Attempt at a Solution
I have tried making graphs for V vs r however it give me a very weird curve. Furthermore, how do I find the coefficient of thermal expansion from potential energy vs interatomic separation distance? All I know is that in a V vs r, if the energy well to the right of the absolute zero is larger than that of the left, the CTE is positive and negative for vice versa.
"see graph 1"
I also try to draw this graph on my graphic calculator but it gives me result similar to y= -1/x
