Levitating balloons demonstrates Bernoulli's principle becuase Bernoulli's principle states that as air moves around an object, it creates different pressures on that object. Faster air means less pressure. Slower air means more pressure. As I blow over the paper, the air on the top is moving faster than the air on the bottom. According to Bernoulli's principle, this faster moving air on the top has a lower pressure than the non-moving air on the bottom. When the paper gets too high, it gets into the air stream which pushes it back down. So the answer would be A: Higher pressure, lower speed air is on the OUTSIDE of the balloon.

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

prolly a beacuse the momentuem the car has increases while going down hill
