Question

As the density of a substance increases, the volume of a given mass of that substance__.
a. Increases
b. is not affected
c. decreases
d. fluctuates

Answer 1

As the density of a substance increases the volume of a given mass of the substance decreases

Answer 2

Answer : The correct option is, (C) decreases

Explanation :

As we know that the density is measured as the mass of substance divided by the volume of substance. The S.I unit of density is, kilogram per cubic meter or $Kg/m^3$

Formula for density :

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

That means the density is directly proportional to the mass of the substance and inversely proportional to the volume of the substance.

As the volume of substance decreases, the density of a substance will be increases and volume of substance increases, the density of a substance will be decreases.

Hence, the correct option is, (C) decreases
