How does the solute absorb temperature from the surroundings?

Explanation:

In endothermic reactions, the net energy from the bonds breaking and forming results in heat energy being absorbed when the solute dissolves in solution. ... So according to Le Chatelier's Principle, the system will adjust to this increase in the heat by promoting the dissolution reaction to absorb some of the heat energy

increased stability in the completion of fluorine's outer shell.
