Answer 1

As the air is removed from the space around the alarm clock, the sound produced by the clock will become fainter. This is because sound waves require a medium (like air) to travel through, and as the air is removed, the sound waves have less medium to propagate through.

However, the appearance of the clock will remain unchanged; you will still see the clock as it is. Therefore, the most accurate response is:

The appearance of the clock will not change, but its sound will become fainter.
