You are presented with the question "What can be used to separate a solute from a solvent in a solution?" and the following answer choices: 
- flow of electrons
 - Dehydration
 - heat energy
 - heating liquids
 - a hydraulic system
 - water vapor
 - kinetic energy
 - Time and energy

Now knowing that evaporation can be used for separating a solute from a solvent in a solution and heating liquids is also made easier by allowing saturated gas to reduce evaporation, choose the best answer.
