You are presented with the question "What can be used to separate a solute from a solvent?" and the following answer choices: 
- liquid drying
 - activation energy
 - a hydraulic system
 - chemical equations
 - Condensation
 - circulatory systems
 - heat energy
 - water vapor

Now knowing that evaporation can be used for separating a solute from a solvent in a solution and evaporation occurs when a liquid dries, choose the best answer.
