I think option one because if the molecules are moving in place, they are tightly packed like a solid. if they are moving around each other, that would mean they could move more freely like a liquid.
It is called The Marsh Test and it was created by James Marsh.
Monomers are molecules whose linkage between them form polymers.
<h3>What are monomers?</h3>
Monomers are molecules that have a low molecular mass.
<h3>Characteristics of monomers</h3>
- When many monomers come together through chemical bonds they form a polymer, which is a macromolecule.
- Natural monomers allow the formation of biomolecules found in living beings.
- Carbohydrates, for example, are macromolecules that are created from the bond established by monosaccharides (monomers).
Therefore, we can conclude that polymers, in short, are chains of monomers -generally joined by covalent bonds-.
