Answer:
Polymerization
Explanation:
Several natural and man-made organic compounds are enormous molecules which contains hundreds of thousands of atoms per molecule.
The giant molecules formed are produced through the process of polymerization.
Polymerization is the linking of monomers through chemical reactions to form long chain polymer molecules.
Monomers are small molecules that are joined to form polymers.
Synthetic plastics are derieved from synthetic polymers. These synthetic materials are very useful and vital due to their great size. Their size premits a certain complexity of structure which makes the molecules disposed in a regular pattern with respect to one another. They stretch out nearly to alongside of one another or coil up independently. The polymerization of monomers to form plastics fosters the various uses these giant molecules are put to.

Explanation:
Answer:
Explanation:
Physical Change:
The changes that occur only due to change in shape or form but their chemical or internal composition remain unchanged.
These changes were reversible.
They have same chemical property.
These changes can be observed with naked eye.
Example
:
Water converting to Ice
Water converting to gas
In this water molecule remain the same only they rearrange themselves that change its state of mater not composition
Chemical changes:
The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.
These changes are irreversible
These changes occur due to chemical reactions
These may not be observed with naked eye
Example:
Combustion of fuel or wood: that oil or wood convert into energy, CO₂ and ash in case of wood
Boiling of egg: that change the chemical composition of protein in the egg
The reaction of Hydrogen and oxygen:
H₂ (g) + O₂ (g) -------------------------------------> 2H₂O (l)
