The sublimation pressure of silver is $2\mathrm{.}955{10}^{-7}Pa$

at $830K.$

a$.$ Predict the sublimation pressure of silver from

$830K$ to its melting point of $1234\mathrm{.}0K$ using the

Einstein model.

b$.$ Repeat the calculation using the Debye model.

c$.$ Compare the results of your predictions with the

known sublimation pressure of $1\mathrm{.}984{10}^{-1}Pa$

at $1224K,$ and with sublimation pressures at

other temperatures that have been correlated

with the equation

$ln{P}^{\text{s}\text{u}\text{b}}(Pa)=29\mathrm{.}635-\frac{34974}{T}-0\mathrm{.}37677ln(T)$
