Agroup of scientists build a net along a section of the river to separate a group of foreign fish species from the rest of the river. they wish to determine
whether their experiment is a closed system by placing a colored dye in the fish's habitat and observing whether the dye escapes from the enclosure.
could this experiment determine whether the system is closed or not? justify your answer based on the definition of a closed system.

This experiment would be unable to determine whether the system is closed or not. This is because the scientists have used a net to separate the sections of a river. Nets have holes in them through which the dye would easily be able to pass. The net would not be able to hold water. Hence, this experiment is not appropriate.

This test will also not be able to determine whether energy flows between the two systems or not.

The experiment could not determine whether the system is closed or not.

Explanation:

The net doesn't hold water. But it is a good part of the experiment for testing whether the system is closed or not with the dye (matter). The problem is that the experiment doesn't test the flow of the energy. And that's an important part to see whether the system is closed or not.
