Please answer the following question: Fact 1: Evaporation can be used for separating a solute from a solvent in a solution. Fact 2: Heating liquids is also made easier by allowing saturated gas to reduce evaporation. Given the two facts above, answer the question "What can be used to separate a solute from a solvent in a solution?" with the following options: - flow of electrons - Dehydration - heat energy - heating liquids - a hydraulic system - water vapor - kinetic energy - Time and energy
A:
heating liquids
