Question

A bucket of warm water can be considered a closed system for a very short period of time.

Which best explains this phenomenon?

Answer 1

A.
The bucket of warm water will eventually turn cold and begin to evaporate.

B.
The bucket of warm water can be easily spilled.

C.
The bucket of warm water can contain different elements.

D.
The mass of the bucket of water will eventually disappear.

Answer 2

Hi Jolin, Although option A seems to be reasonable but none of the options incorporates the "very short period of time" condition that you mentioned earlier. So the bucket cannot be considered a closed system.

Answer 3
