At the top of the mountain, when he tightens the cap onto the bottole, there is some water and some air inside the bottle. Then he brings the bottle down to the base of the mountain.
The pressure on the outside of the bottle is greater than it was when he put the cap on. If anything could get out of the bottlde, it would. But it can't . . . the cap is on too tight. So all the water and all the air has to stay inside, and anything that can get squished into a smaller space has to get squished into a smaller space.
The water is pretty much unsquishable.
Biut the air in there can be <em>COMPRESSED</em>. The air gets squished into a smaller space, and the bottle wrinkles in slightly.
The material is called paramagnetic or non magnetic material. Opposite to this are materials whose magnetic domains are aligned and possess asmagnetism which is due to its ferrous or iron content.
Answer:
Energy Ouput (Useful) / Total Energy Input = 4000 / 4800 = .833
E = 83% assuming 4800 is actually input to fan
