Density of Ice VS water
Ans: Water . When ice is put into water , the ice floats, but when the ice slowly melts, it turns into water as well.
Density Comparison to Water: In chemistry, the density of many substances is compared to the density of water. Does ice float on water or sink in the water? Everyone knows what happens in the case of ice cubes in a glass of water. Look at the graphic on the top.
Why does ice float?
What other observations or facts are known?
- Because ice floats, we can infer that ice must be less dense than water.
- If water is frozen in a glass jar, the glass jar breaks.
- If a pop can freezes, it will also burst.
- From both of the above we infer that the volume of the ice has increased.
Conclusion: The volume of ice must be greater than the same mass of liquid water. Why does the volume increase?
So which is denser ? Ice or water ?Ans: Water . When ice is put into water , the ice floats, but when the ice slowly melts, it turns into water as well.
