A marine biologist measured the amount of heat radiated from an aquarium over the course of an experiment. He concludes that the aquarium is an open system. Explain why this conclusion is invalid.

1) An open system does not exchange energy with its surroundings, and the scientist only measured the exchange of heat.

2) An open system does not exchange matter with its surroundings, and the scientist did not measure the movement of matter.

3) An open system exchanges both energy and matter with its surroundings, and the scientist did not measure the movement of matter.

4) An open system exchanges matter but not energy with its surroundings, and the scientist did not measure the movement of matter.
