Metal pipes used to carry water sometimes burst in the winter. This is because

• A. Water expands when it freezes
• B. Metal contracts more than water
• C. Outside of the pipe contracts more than inside
• D. Metal expands more than water

Answer 1

Answer: (A)

Water expands when it freezes

Metal pipes used to carry water sometimes burst in the winter because of the change in density and volume of the converted form of water under freezing temperature, i.e., ice. Ice has greater volume than water, which causes it to displace more space resulting in metal pipes burst during the winter season.
