Question

Between 0 and 4 degree Celsius

• A. the density of water decreases with temperature
• B. the density of water increases with temperature
• C. the density of water becomes zero
• D. the density of water remains constant with increase in temperature

Answer 1

The correct option is B

the density of water increases with temperature

The density of water increases with temperature between 0 and 4 degree Celsius. This is called as anomalous expansion of water. This is caused by the hydrogen bonding between the oxygen atoms that are negatively charged and the hydrogen atoms that are positively charged, from two different molecules of water.
