Question

Mike is conducting an experiment inside an Erlenmeyer flask, and he has the top of the flask sealed with a balloon to capture any gaseous products that may be produced. Is Mike’s experimental setup an example of a closed, open, or isolated system? Explain your answer in complete sentences.

Answer 1

This is a closed system, for it does exchange energy with the area around it. It will not exchange mass with the surrounding system due to being sealed, but it is not insulated at all.

Answer 2

Closed because the balloon is covering the top of the flask
