E 'WITH Ask Andy How can there be liquid air? "from Bitty Butler, Newport News, Va. The substances that make up our world are solids, liquids or gases because they are governed by the normal temperatures on our planet. The freezing points of the rocks are way above this normal range and so they are frozen solid. With more heat, they can be melted and still more heat turns them to vapors. The freezing and boiling points of water are within the normal temperature range and so we have quantities of ice, liquid water and steamy OOVCU KNOW WHALES WTTERNEDSQNS-UKE SOUNDS OFHIMAPBACK mALES HAVE BEEN RECORDED AND MUSICIANS SWlHg 7TD30MM. vapor, depending upon the weather and climate. However, the boiling points of the gases in the air are all way below any temperature that our planet produces. Hence they remain in their airy, gaseous states. However, we can make things colder than normal. Scientists can even reduce the temperature of the air to its liquifying level. Gaseous air becomes drops of liquid at minus 310 degrees fahrenheit. This shuddering temperature is about 340 degrees colder than the freezing point of water. Hie chilly job is done by using a series of different methods to remove heat from the air. Any substance gets colder simply by losinb its heat. Gases become hotter when they are compressed or squeezed. They become cooler, losing heat, when they spread out and expand. These two tricks are used to remove more and still more heat from ordinary air. First, the air is filtered clean. Then it is piped into a sturdy tank and squeezed under 3,000 pounds of pressure per square inch. This weight is about 200 times heavier than normal air pressure. The crowded gas molecules move faster and the crushed air gets hotter. The next trick is to remove this heat without letting the air gain any more. The cooling procesj is started with currents of co)d water. The somewhat cooler air then is allowed to escape through valves into small pipes that lead to larger pipes. The air spreads out aad as it expands it naturally loses more heat. Then it is returned to the compressor to repeat the squeezing, cooling and expanding processes. The route is repeated several times to remove enough heat to reduce the air to minus 310 degrees fahrenheit. At last, some of it begins to form liquid droplets. They are drained off and stored hi insulated tanks. Otherwise the normal temperature would boil the liquid air back to its gaseous state. Liquid air looks like water, but remember its t e m p e r a t u r e. It freezes a finger beyond repair. When dipped in this innocent-looking liquid, rubber becomes as brittle as glass and lead acts like bouncy rubber. Send questions on postal card to Ask Andy, P.O. Box 2406, Pfeoenix, Arix. S5M2.
