Question 39

During an investigation into the temperature change of a neutralisation reaction, a student sets up the apparatus shown below.

Diagram of a simple calorimeter, showing a polystyrene cup containing a reaction mixture supported inside a glass beaker for stability. A thermometer is placed through a lid into the reaction mixture.

State why a polystyrene cup is used rather than a copper can to hold the reaction mixture.
