Question 37

A student investigated the temperature change when ammonium nitrate dissolves in water.

They poured 100 cm3 of water into a polystyrene cup and recorded the initial temperature.

The student then added 2.50 g of ammonium nitrate to the water, stirred the mixture, and recorded the lowest temperature reached.

Diagram showing a thermometer resting inside a polystyrene cup containing water, which is supported inside a glass beaker for stability.

Give the name of the apparatus that the student should use to measure 2.50 g of ammonium nitrate.
