Polymer Structure and Properties | GCSE Chemistry
Polymers consist of very large molecules made of many repeating units.
Why do polymers have higher melting points than simple molecules?
What is Polymer Structure and Properties | GCSE Chemistry?
"A substance or material consisting of very large molecules, or macromolecules, composed of many repeating subunits."
What is the typical size range of a nanoparticle?
Metals have high melting points because...
As the side of a cube decreases tenfold, what happens to its surface area to volume ratio?
How many covalent bonds does each carbon atom form in diamond?
Large Molecules
Molecules are linked by strong covalent bonds.
Intermolecular forces between polymer chains are relatively strong.
Solid at room temperature due to these forces.
Plastics are a common example of synthetic polymers.
Comparison: Polymers are bigger than molecules like water ($H_2O$) but smaller than giant covalent structures like diamond.
