Question

The density of water is maximum at $4^{\circ }C$,what will happen if its density reduces on cooling?

• A. Volume of water increases
• B. Volume of water decreases
• C. Volume of water first increase and then decrease
• D. Temperature of water remains same

Answer 1

The correct option is A Volume of water increases

Water shows abnormal behaviour as its density is maximum at $4^{o}C$. When the temperature is increased or decreased from $4^{o}C$, its density decreases. On cooling from $4^{o}C$, density of water reduces and volume increases, opposite to other liquids.
