Chemistry: Although the movement of the molecules is spontaneous and random, the net movement of dye is from areas of concentration to concentration and the net movement of water is from areas of concentration to areas of concentration.

$T=1235K=962\°C$

Explanation:

Hello,

In this case, from thermodynamics, it is widely known that the entropy of fusion is defined in terms of the enthalpy of fusion at the fusion temperature (melting point) as shown below:

$\Delta _fS=\frac{\Delta _fH}{T}$

Thus, solving for the melting point:

$T=\frac{\Delta _fH}{\Delta _fS}$

Hence, for silver:

$T=\frac{11.30kJ/(mol)*\frac{1000J}{1kJ} }{9.150J/(mol*K)} \\\\T=1235K=962\°C$

Which is a typical high temperature for a metal such as silver.

Best regards.
