What is distinctive about the size of polymer molecules?
Show answer
They are very large molecules.
What type of bond links the atoms within a polymer molecule?
Show answer
Strong covalent bonds.
The atoms in polymer molecules are linked to each other by strong ? bonds.
Show answer
covalent
How strong are the intermolecular forces between polymer molecules?
Show answer
Relatively strong, because the molecules are very large.
What is the state of polymers at room temperature?
Show answer
Solid.
Why are polymers solids at room temperature?
Show answer
The intermolecular forces between the large polymer molecules are relatively strong, so a lot of energy is needed to separate them.
Polymers are ? at room temperature because their intermolecular forces are relatively strong.
Show answer
solids
Which forces hold neighbouring polymer molecules together?
Show answer
Intermolecular forces (not covalent bonds), which are relatively strong in polymers.
