Vedclass · Answer

(D) Water exhibits a unique property known as anomalous expansion.As water is cooled from room temperature,its density increases until it reaches $4^\circ 	ext{C}$.At $4^\circ 	ext{C}$,the water molecules are packed most closely together,resulting in the maximum density of $1 	ext{ g/cm}^3$.Below $4^\circ 	ext{C}$,the hydrogen bonding structure causes the water molecules to move slightly further apart as they begin to form a crystalline lattice structure (ice),which causes the density to decrease.Therefore,the density of water is maximum at $4^\circ 	ext{C}$.
