Agroup of scientists build a special enclosure in the local bay to separate their experiment from the rest of the ocean. they wish to determine whether their experiment is a closed system by using a colored dye that is placed in the water. what result would best indicate that their experiment is a closed system, and why?

If there is no dye coming out of the enclosure going into the ocean they can be sure that the enclosure is indeed a closed system.

Hope this helped:)

In chemistry, especially in thermodynamics, a closed system, in contrast to an isolated system, is a system enclosed by a boundary that allows energy but not matter exchange between the system and its neighborhood. In other words, this type of system does not exchange with the surrounding environment, so it does not receive any influence from the environment and on the other hand it does not influence.

Thus, we can conclude that the best result to indicate that the experiment is a closed system is that the dye placed in the experiment did not escape into the environment outside the experiment, in the same way that no environmental material entered the experiment.

i know can you plzz me with this question im sorry i didt answer your question i just need hel.
