Question
One special physical property of water is that when water becomes solid(ice), it expands because the volume increases and the density:Question 6Select one:A.Increases and it floats in waterB.Decreases and it floats in waterC.Increases and it sinks in waterD.Decreases and it sinks in water
Solution
The correct answer is B. Decreases and it floats in water.
Here's why:
-
When water freezes into its solid form (ice), the molecules arrange themselves in a way that takes up more space. This is why the volume of water increases when it freezes.
-
Density is the mass of an object divided by its volume. Since the volume of water increases when it freezes (and the mass stays the same), the density decreases.
-
Objects with a lower density than the liquid they are in will float. Since ice has a lower density than liquid water, it floats.
