Abstract
At first, we discuss what is meant by equilibrium phase transition and nonequilibrium one. For equilibrium phase transition the concentration of an unfrozen water W coincides with Heaviside’s function W(x,t) = H(u(x,t)), here u(x,t) is the temperature,
u= 0 is the melting temperature. This means that under change of temperature u the concentration of water W takes instantaneously a new value corresponding to the new temperature. Meanwhile in real processes some finite time is required for achieving equilibrium between ice and an unfrozen water in the ground.
