Why will some pipes burst with freezing temperatures?

• Water condenses in colder temperatures, causing the metal to shrink and burst

• Water expands in colder temperatures, causing pressure inside the pipes, making it burst

• Water becomes acidic in colder temperatures, causing corrosion of the pipes, making it burst

• Water becomes basic in colder temperatures, causing corrosion of the pipes, making it burst
