Measurement of Density
The mass is normally measured with an appropriate scale or balance.
The volume may be measured directly (from the geometry of the object) or by the displacement of afluid.
Hydrostatic weighing is a method that combines these two.
2. Specific Gravity
It is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference materia
Synthesis
Grafting onto
“Grafting-onto” involves the chemical reaction preformed, functionalized polymers with surfaces containing complementary functional groups
Grafting from
‘‘Grafting-from’’ involves an in situ polymerization of an initiator functionalized surface with monomer.

We have a tendency to think CO2 is negative. Because of Global warming. But, In other face, CO2 is very useful to use.
As you can see we use Co2 in various ways. For example, in our lives, we can see Co2 in beverages, and in concert, we see Co2 in form of gas.
Anyway, Today I explain to you about this, Electrochemical reaction. We convert Co2 to other materials using electrochemical reaction.
