Many items in a kitchen are made from polymers.
The table shows some kitchen items and the polymer each one is made from.
| Item | Polymer |
|---|---|
| cling film | poly(ethene) |
| non-stick coating on a frying pan | PTFE |
| sink waste pipe | PVC |
| microwave food container | poly(propene) |
Give one property of PTFE that makes it suitable for a non-stick coating on a frying pan.
Give one property of poly(ethene) that makes it suitable for cling film.
Give two properties of PVC that make it suitable for a sink waste pipe.
Suggest why poly(propene), rather than poly(ethene), is used to make microwave food containers.
