Question

4. What is mass?
5. What is volume?
6. What is density?​

Answer 1

Answer:

4. Mass, in physics, quantitative measure of inertia, a fundamental property of all matter.

5.the amount of space that something contains or fills.

6. Density is a measurement that compares the amount of matter an object has to its volume.

$\Large\bold\color{aqua}Mass$

Mass is a quantity that tells us how much force is required to accelerate an object.

$\small\fbox\blue{Mass \:= \:Force\: ×\:Acceleration}$

Since force = change in momentum / change in time, it also tells us how much force a moving object could potentially have if it were accelerated, mass = energy * a constant.

$\Large\bold\color{aqua}Volume$

The space occuppied by a matter of given mass, in the three dimensional space, is called the volume. Volume is the amount of space a substance occupies.

$\Large\bold\color{aqua}Density$

Density is defined as mass per unit volume. i.e. for a given volume, the amount of matter present in it determines the density. More the matter for a given volume, more the density. To calculate the density of an object, simply divide its mass by the volume of the object.
