The density of an object is defined as its mass divided by its volume. Mathematically, density = Mass / Volume. The unit of density is kilogram per cubic meter, kg / m^3 or g /cm^3.
For the question given above: the
Mass = 200.0 g
Volume = 100.0 cm^3
Therefore, Density = Mass / Volume = 200 / 100 = 2
Thus, the density of the object is 2 g /cm^3.

* sorry I didn't know Q. 8/9
The amount of absorption force is not same at all time and at all where .
It has difference at different time periods
So during those the curve goes up and down and repeat this flow
So there are dips
Answer:
Its a natural resource used around the world
Boiling points are a measure of intermolecular forces. The intermolecular forces increase with increasing polarization of bonds. Boiling point increases with molecular weight, and with surface area.
