Making a mixture is a physical change and, therefore, mixtures can be separated by physical means.
Answer: Option D
Step-by-step explanation:
Mixtures are combination of two or more substances irrespective of their state of matter. The mixtures can be classified as solution, suspension and colloids. In mixtures , the combining substances will retain their chemical properties, they will combine only physically and not chemically.
So the chemical properties of the mixture will be the chemical properties of each of its constituent. As mixtures form by physical change of the combining substances, they can be separated by physical means only like distillation, evaporation etc.
Thus, making a mixture can be physically changed and therefore mixtures can be separated by physical means.
