In reality, for any substance in solid-liquid equilibrium, if pressure is applied on the system, it will shift towards the side having less volume i.e. more density(according to LE-CHATELIER'S PRINCIPLE). But for water and Gallium density of solid state<liquid state. So on applying pressure, equilibrium shifts towards liquid state.

When we apply pressure on something then it undergoes compression by a force. This force tends to bring the ice molecules come together, molecules lose energy which lowers the melting point.

Thank You!
