Why do frozen water pipes burst? Would a mercury thermometer break if the temperature went below the freezing temperature of mercury? Why or why not?
Relation of volume to temperature
The Attempt at a Solution
Water has its minimum volume at 4°C. Therefore, when the temperature drops below 4°C, the volume of the water increases continuously. Therefore, frozen water pipes burst.
Mercury contracts when cooled, so a mercury thermometer would not break if the temperature went below the freezing temperature of mercury.
Are these answers correct?
