Question 35

A student investigates the temperature change when zinc powder is added to copper(II) sulfate solution in a polystyrene cup.

Figure 1 shows the apparatus used.

A diagram of a reaction calorimeter. It shows a polystyrene cup placed inside a glass beaker for stability. The cup contains a reaction mixture. A lid with two holes covers the cup. A stirrer is inserted through one hole. Through the other hole, a thermometer labeled Y is inserted into the reaction mixture.

State the name of the piece of apparatus labeled Y that is used to measure the temperature change.
