Question

7. The density of steel is 7.9 g/m' and the
density of lead is 11.34 g/m! Which of the
following statements is true?
a) The volume of lead is greater than the
volume of steel for the same mass.
b) The mass of lead is greater than the
mass of steel for the same volume.
c) Equal masses of lead and steel have the
same volume.
d) Equal volumes of lead and steel have the
Same mass.​

Answer 1

The mass of lead is greater than the  mass of steel for the same volume

Therefore, option (b) is correct.

Explanation:

Density of Steel = 7.9 gm/cm³

Density of Lead = 11.34 gm/cm³

We know that

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

In option (a)

If we take mass as equal then density if inversely proportional to volume

i.e. The volume of steel will be more than that of lead because the density of steel is less than that of lead

Thus, option (a) is incorrect.

If we take volume as equal (constant) then Density is directly proportional to mass

i.e. mass of Lead will be more than mass of steel because density of lead is more than density of steel.

Therefore, option (b) is correct.

Hope this answer is helpful.
