Quizplus · Accepted Answer

When water is cooled, it contracts until it reaches a temperature of 4°C, after which it expands as it freezes into ice. This is due to the unique structure of ice, where the water molecules are arranged in a crystalline lattice with empty space between them. As the temperature decreases, the water molecules slow down and the empty spaces between them increase, causing the ice to expand. Therefore, ice water is the only option that expands when the temperature is lowered.
