The best response is: The appearance of the clock will not change, but its sound will become fainter.
As air is removed from the jar, the sound of the alarm clock will become fainter because sound waves require a medium (like air) to travel through. With less air, the sound waves are less effective in propagating, making the clock's ringing quieter. The appearance of the clock remains unchanged.
