Thermal energy is required to help the salt separate from water through the process of distillation.
Option D
Explanation:
- When salt is mixed with water it gets completely diluted and mixed with the water here as salt is completely soluble.
- In order to separate the salt from the water, the water needs to be boiled so that the water with the help of thermal energy can get translated to water vapor and evaporate out from the solution leaving the salt particles intact.
- After evaporation, the salt is cooled and therefore complete separation occurs.
