Question

While Gina conducts a calorimetry investigation, she observes the temperature change of a reaction in a sealed, insulated calorimeter. Would you consider the calorimeter an example of a closed, open, or isolated system? Explain your answer in complete sentences.

Answer 1

Usually, The calorimeter is a closed system, with the known mass of the sample and oxygen, form a closed system - no air escapes during the reaction

In a closed system, no mass may be transferred in or out of the system boundaries. The system will always contain the same amount of matter, but heat and work can be exchanged across the boundary of the system. Whether a system can exchange heat, work, or both is dependent on the property of its boundary.
