4. (10 points) A phase transformation from liquid to solid is taking place at a temperature T which is less than the melting temperature Tm. a) Explain why the rate of phase transformation exhibits a non-monotonic dependence on temperature and attains a maximum value at some temperature? b) Obtain the temperature in terms of Tom)) at which the number of critical nuclei formed is maximum. Assume that the enthalpy difference between the two phases is independent of temperature
