Question

Describe what is meant by physical properties Using a salt water solution , describe how one could change two different physical properties and not alter the chemical nature ofthe salt water

Answer 1

Answer: Changing the amount of solute and volume of solvent we can change physical properties of the given salt water solution.

Explanation:

Physical properties are defined as the properties which does not cause any change in chemical composition of a substance. For example, density, mass, volume, etc are all physical properties.

When we take a salt water solution then on adding more amount of salt into the water there will occur change in density of the solution as density is mass present per liter of solution.

Also, if we add more amount of solvent then there will occur change in volume of the solution.

Hence, in both the cases physical properties of the solution are changing and no change in its chemical composition is taking place.
