　　【练习】

　　Most people would describe water like a colorless liquid. They __1

　　would know that in very cold conditions it becomes a solid called

　　ice and that when heating on a fire it becomes a vapor called steam. __2

　　However, water, they would say, is a liquid. We have learned that

　　water consists of molecules composed with two atoms of hydrogen __3

　　and one atom of oxygen, which we describe by the formula H2O.

　　This is equally true of the solid called ice and the gas called steam.

　　Chemically there is no difference between the gas, the liquid, and

　　the solid, all of which is made up of molecules with the formula H2O. __4

　　This is true of other chemical substances; most of them can exist as

　　gases or as liquids or as solids. We may normally think of iron as a

　　solid, but if we will heat it in a furnace, it will melt and become a __5

　　liquid, and at very high temperatures it will become a gas. Nothing

　　very permanent occurs when a gas changes into a liquid or a solid.

　　Everyone knows that ice, which has been made by freezing water,

　　can be melted again by warmed and that steam can be condensed __6

　　on a cold surface to become liquid water. In fact, it is only because

　　water is so a familiar substance that different names are used for __7

　　the solid, liquid and gas. Most substances are only familiar with __8

　　us in one state, because the temperatures requiring to turn them __9

　　into gases are very high, or the temperatures necessary to turn them

　　into solids are so low. Water is an exception in this respect, which

　　is another reason why its three states have given three different names. __10
