Question

Alexis is observing a reaction that is taking place in an unsealed glass beaker. Is Alexis's experimental setup an example of a closed, open, or isolated system? Explain your answer in complete sentences.

Answer 1

It is an open system.

- Closed system is a physical system which allows to exchange energy with the surrounding but not allows to exchange matter.

- Isolated system does not exchange either matter or energy with the external environment.

- Open system is a type of physical system which allows to exchange both matter and energy with the surroundings.

Hence, Alex's experimental setup which has an unsealed beaker is an open system.
