Answer 1

Distillation, for the water to be seperated it must be heated to break the chemical bond. 

Answer 2

Answer: Heat energy must be required to start the distillation process.

Step-by-step explanation:

Distillation is the process by which a mixture of substances can be separated from each other.

In this process the mixture of salt and water is kept in a container and heated upto a certain temperature. This is done at a certain temperature where the water starts boiling and evaporating.

In this process heat energy is used to boil water and evaporate it, so that only salt is left over in the container.
