Question

A can of soft drink at room temperature is put into a refrigerator so that it will cool. The can of soft drink should be analyzed as a(n) _____ system.

Answer 1

Answer:

Closed

Explanation:

Metal is a good conductor of electricity and heat.

• In electricity terms, electricity will work in the closed circuits so only close loops will work.

• In open circuits there is no flow of electricity because of no continuous loop.

If the cooling of the can is taken place, then the heat is flowing out of the can into the fridge while cool air from the fridge is flowing into the can form a loop.

Therefore, the can of the soft drink is a closed system.
