Equilibrium in Physical Process

The video tutorial discusses various types of equilibrium, focusing on solid-liquid equilibrium. It describes an experiment with solid ice and liquid water in a thermo flask at 273 Kelvin and one atmospheric pressure, where both phases are in equilibrium. The mass of ice and water remains constant, and molecular interactions at the boundary are observed. The rate of phase conversion is equal, maintaining equilibrium. The melting point is defined as the temperature where solid ice and liquid water coexist at one atmospheric pressure.

How does the rate of conversion between solid ice and liquid water relate to the concept of equilibrium?

Explain the concept of melting point in relation to solid ice and liquid water.
