Question 52

A student investigates the temperature change during a displacement reaction using the apparatus shown in the diagram below.

Diagram of a student's calorimetry setup. A digital thermometer is placed through a tight-fitting plastic lid into a liquid reaction mixture. The reaction mixture is contained inside a cup, labelled X. This cup is placed inside a sturdy glass beaker, labelled Y, which provides physical stability.

The reaction container, labelled X, is made of expanded polystyrene.

State why expanded polystyrene is a more suitable material than copper for this container.
