Water can dissolve other substances. Which factor best contributes to this property of water?
d. Water particles are not fixed in place.
Explanation: -
When a substance like say common salt sodium chloride NaCl is dissolved in water, the water molecules surround the Na⁺ and Cl⁻ which result from dissolving of NaCl in water.
The water molecules by surrounding the Na⁺ and Cl⁻ help in dissolving NaCl.
Thus in order to surround them,the water molecules should not be fixed in their place and be free to move about.
