A marine biologist measured the amount of heat radiated from an aquarium over the course of an experiment. He concludes that the aquarium cannot be considered an isolated system. What could he do to make the aquarium an isolated system?

A.He could add a heating element to the aquarium to compensate for heat lost through radiation.
B.He could add insulation to the aquarium so that it does not exchange energy with its surroundings.
C.He could add light to the aquarium so that the system's total energy change remains the same.
D.He could add living organisms to the aquarium so that natural heat is generated by the system.

I believe the correct answer from the choices listed above is option B. For him, to make the aquarium an isolated system, he could add insulation to the aquarium so that it does not exchange energy with its surroundings. Hope this answers the question. Have a nice day.

Answer: The correct answer is B. He could add insulation to the aquarium so that it does not exchange energy with its surroundings.

Explanation-

Isolated system is a system in which there is no exchange of energy and mass. As per the question, heat is radiated from the aquarium. In order to make it an isolated system, insulating or diathermic cover is used over it so that it does not exchange energy with its surroundings.
