Select the correct answer.

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 used in the distilling process?

A. chemical energy
B. electrical energy
C. mechanical energy (motion)
D. thermal energy



Answer :

Final answer:

Distillation is a physical process that separates mixtures based on boiling point differences, such as separating salt from water. The separation of salt and water through distillation involves the conversion of thermal energy.


Explanation:

Distillation is a process used to separate mixtures based on differences in boiling points, where heating the mixture causes the more volatile component to vaporize and then condense back into a liquid form.

When salt is dissolved in tap water and then distilled, the water separates from the salt due to differences in volatility, demonstrating a physical separation.

This separation process involves the conversion of thermal energy to facilitate the separation of the components of the mixture.
