Best answer
Correct Answer - Option 3 : Physical change

The correct answer is Physical change.

 

  • Dissolving a solid in liquid, such as table salt in water, is a physical change because only the state of the matter has changed.
  • Physical changes can often be reversed.
  • Allowing the water to evaporate will return the salt to a solid-state.
  • It has not combined with the water to cause a chemical reaction.
