it has some thing to do with the LeChtelier principle

because heat helps the solid dissolve faster.

If you increase thermal energy to an object, it excites the atoms more. The more excited an atom is, the easier it is for the atom to break away from the other atoms.
If you boil a solid thing in water, the object will have a weakened electrical bond with all of it's atoms, because the atoms are all jumping around.
That, mixed with the movement of the water boiling, and the solid object is much more likely to break apart than it would if it was in normal water.

sure, a upward thrust in temperature will easily bring about a upward thrust of solubility for any given substance in a liquid, provided the liquid has no longer yet reached its saturation element. a similar applies to a upward thrust in rigidity. in certainty, the terrific thank you to help solubility is to enhance the two the temperature AND the rigidity, that's the concept in the back of the rigidity cooker.

The particles of the solute and solvent have more kinetic energy, thus causing the molecules or ions to be removed much easier from the solid particles.

increase temperature means increase in kinetic energy for individual molecules, therefore enough energy to break bonds

It would only do this if the enthalpy of solution was endothermic.
