Question

The density of iron is more than that of cotton why?

Answer 1

By mass, 1 kg of iron and 1 kg of cotton weigh same i.e none is heavier. You wont find any difference in the effort you need to put to lift each of them.

However, since the densities are different (iron has higher density), the volume occupied will be different. 1 kg of iron has lesser volume than 1 kg of cotton.

Answer 2

Hey!

We know that,

Density = Mass/Volume

If we take 1kg of iron and 1 kg of cotton, Mass is same but volume occupied by each of them is different.

Density is inversely proportional to volume. The higher the density, the lower the volume. Iron occupies less volume than cotton, that's why it has higher density comparatively to Cotton.
