Answer:
This question is incomplete
Explanation:
The process described in which the solution absorbs thermal energy is referred to endothermic reaction. Endothermic reaction is a reaction that absorbs heat/thermal energy.
The other two processes mentioned will have to be determined based on the options provided. However, what appears to be the case, based on the construction of the question, is that the question describes types of saturation (saturated, unsaturated and supersaturated solutions).
Saturated solution: This is a solution that contains just the amount of solute that that the solvent can dissolve and any further addition of solute will leave the solute undissolved at the floor/base of the solution.
Unsaturated solution: This is a solution that contains less solute than the solvent can actually dissolves
Supersaturated solution: This is a solution that contains more solute than the solvent can dissolve, leaving the undissolved solute around the solution.
