Two identical cylindrical vessels with their bases at the same level, each contains a liquid of density \[1.3\times {{10}^{3}}kg/{{m}^{3}}\]. The area of each base is \[4.0\text{ }c{{m}^{2}}\], but in one vessel, the liquid height is 0.854 m and in the other it is 1.560 m. The work done by the gravitational force in equalizing the levels when the two vessels are connected is _____ J.
