Question

3. why Ice float over water? ​

Answer 1

ice floats on water because It has low density so it floats on water

Answer 2

$\huge\fcolorbox{black}{black}{answer}$

Though ice is solid, it has a cage-like structure hence there are a large number of empty spaces between its particles. ... Hence, the density of ice is less than that of water. A substance with lower density than water can float on water. Therefore, ice floats on water.
