Question

It is often seen that a lighter object floats over water,how?

Answer 1

Answer:

Explanation:

We know that density of water is 1g/CC .so, the object floating on it should have less density than the water .

For example,

We know that ice floats on water

There fore

Density of water is 1g/CC and

Density of ice is 0.9g/CC

So, density of ice is less than density of water.

Answer 2

Answer:

Things float when they are positively buoyant, or less dense than the fluid in which they are sitting. This does not mean that an object has to be lighter than the fluid, as in the case of a boat; objects just need to have a greater ratio of empty space to mass than the fluid.
