Suppose that the forces holding an atom in its position in a crystal are the same for two different monatomic solids, but the mass of an atom $m$ is larger for solid $B$ than for solid $A$. Which has the larger value of $T_{E}$ ?
A) Solid $A$
B) Solid $B$
C) Both have about the same value of $T_{E}$.

Quizplus · Accepted Answer

The Einstein temperature $T_{E}$ is inversely proportional to the square root of the atomic mass. Since solid $A$ has a smaller atomic mass than solid $B$, it will have a larger $T_{E}$.
