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

Table 1

Property	High-density poly(ethene) (HDPE)	Poly(vinyl chloride) (PVC)
Density in $g/cm3\text{g/cm}^3$	$0.96$	$1.44$
Temperature at which polymer completely melts in $∘C^\circ\text{C}$	$130$	$210$

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 $^\circ\text{C}$ . Explain why HDPE is not suitable for making containers used in this process, using the data in Table 1.
