Question

Liquid generally have lower density as compared to solids. But you must have observed that ice floats on water. Find out why?

Answer 1

Explanation: Density=Mass/Volume

As the volume of a substance increases, it's density decreases.

Though Ice is a solid, it has large number of empty spaces between its particles.

These spaces are longer as compared to the spaces present between the particles of water. Thus, the volume of ice is greater than that of water. Hence, the density of ice is less than that of water.

And we know that a substance with lower density than water can float on water. Therefore, ice floats on water.

$\large\green{\underline{\underline{\mathscr{\red{\:\:\:\:\:Answer\:\:\:\:\:}}}}}$

Density of ice is less than the density of water.The low density of ice can be attributed to the small pores it was which allows it to trap air.Hence ice floats on water.
