Jack is testing how sound travels. damon stood on the opposite side of the room and whispered a sentence to him. then, jack held a balloon to his own ear as damon whispered the sentence to him again. jack heard the sentence better the second time. how did the balloon affect the sound of damon's whisper? a) the latex the balloon is made of makes sounds seem louder. b) there is no air pressure inside the balloon, so it created a vacuum that made the sound louder. c) the pressure inside the balloon is less than the pressure inside jacks's ear, making the sound echo the second time. d) sound travels better through the compact molecules of air inside the balloon than the less compact molecules on the outside.
