1 answer
As the air is slowly removed from the space around the ringing alarm clock, the sound produced by the clock will become fainter. This is because sound requires a medium (like air) to travel through, and with less air, the sound waves will not be able to propagate as effectively. However, the appearance of the clock will remain unchanged.
Therefore, the correct response is:
The appearance of the clock will not change, but its sound will become fainter.
