Table 1 shows some properties of the polymers high-density poly(ethene) (HDPE) and poly(vinyl chloride) (PVC).

Determine the simplest whole number ratio of the density of poly(vinyl chloride) (PVC) to the density of high-density poly(ethene) (HDPE).
Industrial chemical containers are cleaned using superheated steam at a temperature of 150∘C150 ^\circ\text{C}150∘C. Explain why HDPE is not suitable for making containers used in this process, using the data in Table 1.
