polymers

• What are polymers made up of?


  Polymers are made up of smaller units called monomers.
• What is an example of a polymer mentioned in the video?


  Polypropylene is an example of a polymer mentioned in the video.
• How long can a single molecule of polypropylene be?


  A single molecule of polypropylene can be thousands of atoms long.
• What is the formula for the monomer propine?


  The formula for propine is $C_3H_6$.
• How do monomers combine to form polymers?


  Monomers combine by adding together repeatedly to form a polymer chain.
• How can you identify a repeating unit in a polymer?


  You can identify a repeating unit by picking out a small section that seems to repeat.
• What does the letter 'n' represent in polymer notation?


  The letter 'n' represents how many repeating units there are in the overall polymer.
• What notation is used to draw repeating units in polymers?


  Curved brackets are used to draw repeating units in polymers.
• What type of bonds are present within polymers?


  Polymers contain covalent bonds, which are very strong.
• What needs to be broken to melt or boil polymers?

  To melt or boil polymers, the intermolecular forces between separate polymer molecules need to be broken.
• How do the melting and boiling points of polymers compare to giant covalent structures?


  Polymers have lower melting and boiling points than giant covalent structures like diamond.
• Why are polymers generally solid at room temperature?


  Polymers are generally solid at room temperature due to their strong intermolecular forces and high surface area.
• What are the two main types of polymers mentioned in the video?

  • Addition polymers
  • Condensation polymers
