Most full scuba tanks have a pressure of between 1,800 p. s.i. and 3,000 p. s.i. (pounds per square inch). approximately 70 to 85 cubic feet of air has been squeezed into the tank. when a diver takes his air tank to be refilled, the dive shop will hook his tank to a compressor with a pressure hose and place his tank in a tub of water while it is being filled. what reasons can you give for placing the tank in water?
