Question

The space occupied by the object is called
(A) Area
(B) Mass
(C) density
(D) volume

Answer 1

Hint
The space inside any object is the same as the quantity of something filled inside that space. More quantities of the object can be filled inside the object if the object's size is large.

Complete step by step answer
Consider a hollow object in which the inside space of the object is empty. The empty space of the object is called the volume of the object. The volume of the object changes with the size of the object. If the size of the object is more, the volume of the object also becomes more.
The volume of an object having some mass and density can be evaluated by using following expression,
$V = \dfrac{m}{\rho }$
Here, $m$ is the mass of the object and $\rho $ density of the object.
The value of volumes depends completely on the shape and size of the material, so for different shapes of objects, the value of volume will be different. Like for a cubical shape object of side$s$, the volume will be ${s^3}$ and cuboid shape object of length $L$, width $B$ and $H$, the volume will be $L \times B \times H$.
The volume depends on the state of the material of the object. The volume of the solids is less than the liquids and gas volume because the distance between the atoms of the material in solid is less than in the liquid and gas. The atoms of the solid are bound by the strong attraction force of the atoms. The attraction force for the atoms of gas and liquid is less, so liquid and gas are compressible.
Therefore, the space occupied by the object is called the volume of the object and option (D) is correct.

Note
The volume depends on the density for the same amount of the mass. The denser material occupies less volume than the less dense for the same mass of the object.
