Concept:Water has unique physical and chemical properties. Its density is maximum at 4°C, not at 100°C.
Explanation:Water is called a universal solvent because it can dissolve many substances due to its polarity. This statement is true.
Water has the capacity to dissolve a variety of different substances. This is also true.
Water exists in all three stages of matter: solid (ice), liquid (water), and gas (steam or vapour). This is correct.
However, the density of water is maximum at 4°C, not at 100°C. At 100°C, water is boiling and its density is lower than at 4°C.
Therefore, the statement in option C is not true.
Answer:Option C (Density of water is maximum at 100° C) is not true about water.
