Question

which will have more density one gram of cotton or one gran of iron ? explain

Answer 1

The density of one gram iron is
greater than the density of one
gram cotten because the partical
of iron are more closser than the
partical of cotten in o e gram.

Answer 2

Answer: Density of one gram of iron is more than the density of cotton.

Explanation:

Density is defined as the ratio of mass and volume of an object.

Mathematically,

$Density=\frac{Mass}{Volume}$

As, mass of both the substances is given to be same, so the density will depend on the volume of the two substances.

Volume of iron is less than the volume of cotton, because in iron, the particles are closely packed and it occupies less space. While in cotton, there is vacant spaces between the particles and hence, it occupies more space.

From the above expression, it is visible that volume is inversely proportional to density. More the volume, less the density and vice-versa.

Hence, one gram of iron is more than the density of cotton.
