　　 prove light is bent when passing the sun

　　 won the Nobel Prize for Physics in 1922

Evaluation: one of the greatest scientists in the 20th century

　　　 Albert Einstein

Albert Einstein was born on March 14th,1879 in Germany. When he was a child,he was curious about everything, but he was considered to be slow at learning. In 1886, he began to study in Munich. He studied mathematics as well as religion. In 1896,Einstein graduated from high school at the age of 17.

Four years later, Einstein became a maths teacher. In 1905, he received a doctor’s degree. By the year 1915, he had developed the famous Theory of Relativity and became famous in the world. He proved that light is bent as it passes the sun. Because of his great achievement, he won the Nobel Prize for Physics in 1922.

Einstein was one of the greatest scientists in the 20th century. Some people say that he was a genius. But I think the main reason why he was so successful was his hard work .

2．按時間順序

19、(1)m_(高溫)=15.6g　　 m_(低溫)=36.9g　　

(2) KNO₃和NaCl　　 15.6g　　 36.9g

18、36 g

17、(1)100 g　　 (2)47.5%

16、(1)NaHCO₃；129 g

(2)NH₄Cl 和NaHCO₃；30.7 g

15、600 L；76.1 L；加蒸餾水稀釋至600 L。

講析：溶液的稀釋或混合過程中，“溶質(zhì)”是個關(guān)鍵。稀釋時溶質(zhì)不變，可得

c V =c₁V₁；混合時溶質(zhì)變化，有c V = c₁V₁ + c₂ V₂

14、C；C；G。

講析：晶體在其飽和溶液中一方面是晶體溶解，另一方面是溶液會析出晶體，存在著溶解結(jié)晶平衡。
