C. a bit more than 104g, because ice takes up more space than water
When water freezes into ice, it expands and takes up more volume than when it was in liquid form. Therefore, the weight of the bottle with solid ice should be slightly more than the weight of the bottle with liquid water.
Students are investigating how freezing liquid water into solid ice affects the weight of the water. They put 100 mL of liquid water in a large plastic bottle. They measured the weight of the bottle with liquid water to be 104g. Then they put the bottle with liquid water in a freezer.
When the water in the bottle froze into solid ice, they took it out and measured the weight again.
What should be the weight of the bottle with solid ice?
• A. less than 104 g, because ice floats on water
B. the same 104 g, because it has the same amount of matter
• C. a bit more than 104g, because ice takes up more space than water
• D. a lot more than 104 g, because solids are much heavier than liquids
