=// [] //= = = =What makes ice float?= = = =My topic for this interesting project is to explore the reason why ice floats. Any substance floats if it isn't as dense, has less mass per unit of volume, than the other components compared to it. For an object to float, it must displace a fluid weight equal to its own weight. Ice floats because it is less dense than liquid water itself, by around 9%.Molecules in water are made of one oxygen atom, and two hydrogen atoms. When water cools to 4 degrees celcius, the molecules bond to change the negative atoms to be apart. If ice didn't float, instaed of only the top of the bodoy of water freezing, the entire body of water would freeze, from top to bottom.=


 * Did you know? without water freezing into ice, the 75% of the world covered in water would completely freeze.**
