Question

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 required to begin the distilling process? a. chemical energy b. electrical energy c. mechanical energy (motion) d. thermal energy

Explanation:

Distillation of a salt - water mixture involves heating the mixture. Heating is a form of thermal energy application. When the water - salt mixture is heated, water evaporates leaving the salt behind as it has a much higher boiling point. Thermal energy is used to increase the kinetic energy of water molecules to the point where they change from the liquid to the gaseous state.

Answer:

D. thermal energy
