Wind speed is determined by ________. a) latitude b) pressure gradient force c) parallax d) random motions of gas molecules e) Coriolis effect

b) pressure gradient force

As shown in the video, what causes the item to deflate? Hints a) It gets heated up, which causes the air inside to expand. b) It slowly seeps out over many hours. c) The higher pressure inside the item forces the air out into the lower pressure of the room. d) When the passage is blocked, the air has nowhere else to go. e) It explodes.

c) The higher pressure inside the item forces the air out into the lower pressure of the room.
