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

A sealed, insulated calorimeter is considered as an example of a isolated system.

Explanation:

There are three types of system:

An open system is a system which allows free exchange of energy and matter with its surroundings.

A closed system is a system which allows only exchange of energy with its surroundings and not matter.

An isolated system which neither allow exchange of energy nor matter with its surroundings.

Thus in a sealed, insulated calorimeter which do not allow exchange of matter or energy is an example of isolated system.

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
