Question

Salt is dissolved in a flask of tap water. Distilling the mixture causes the salt to separate from the water. Which type of energy is required to begin the distilling process?

Answer 1

Answer: D) Thermal Energy

Step-by-step explanation:

In distillation, the solution is first heated, where heat energy is required, such as using a Bunsen burner.

When the solution is heated, the water may reach its boiling point and evaporate. However, salt does not. When water molecules evaporates, it travels through a condenser that cools it down into liquid again. Therefore we get pure water. Salt is also obtained in the original beaker.

Therefore to first start this process, Thermal energy is required.

Answer 2
