Explanation of Solution

Introduction:Polyethylene is a synthetic polymer.

Consider the figure provided in the question.

The first object is a glove made of low-density polyethylene (LPDE), as it is thinner, tough, slightly opaque and flexible material. It is also inexpensive.

The second object is a pan made of polytetrafluoroethylene, a type of polyethylene, also known as Teflon.This material is used to make kitchenware as it is non-sticky, water resistant, corrosion resistant, and heat resistant.

Conclusion: the glove is made of low-density polyethylene (LPDE) and the pan is made of polytetrafluoroethylene (Teflon).
