Question

A student is performing an experiment to study thermodynamics. The student mixes citric acid and sodium bicarbonate in a calorimeter to determine the energy released in the chemical reaction. In one paragraph, identify the system, the surroundings, and the reasons for using calorimetry in this type of experiment.

Answer 1

Explanation :

In thermodynamics, a system is region or part of space which is being studied and observed while the surrounding is the region or space around the system which interacts with the system.

Here in the experiment ,system which is observed is reaction or changes when citric acid and sodium bicarbonate are mixed together. And the mixing is carried out in the calorimeter which serves as a surrounding around the system.

The reason behind the using the calorimeter is measure the energy change occurring during the reaction.
