Questions 9-18


·Read the following passage and answer questions 9-18.
1. From Dr. R. S. Scorer of Britain’s Imperial Collage of the Science comes the latest theory about the lighting flashes. Dr. Scorer believes the cause is haft failing through super cooled clouds. Ice particles bouncing off the falling hail acquire a positive charge and rise to the top of the cloud while the hail carries a negative charge to the bottom of the cloud.
2. According to Dr. Scorer, Benjamin Franklin first proved thunderclouds are charged with electricity. Later investigations showed that the tops of the clouds have a great positive charge and the bottoms have great negative charge.
3. When the charges became great enough to break the insulating properties of the air, lighting flashes carry the electricity within the cloud, or from cloud to cloud, or from cloud to earth. But the question remained: How do the charges develop within the cloud.
4. To seek the cause, Dr. Scorer and his colleagues at the college first duplicated thundercloud current in a liquid tank. They found the mixture takes place only in the tops of the clouds.
5. Next a study of thunderclouds over the North Atlantic showed that the lighting occurs only when the temperature around cloud is below freezing. Particles at the top of the clouds begin to freeze but those in the remainder of the cloud stay unfrozen although below freezing temperature. In the laboratory, S.E. Reynolds whirled a refrigerated rod through ice particles and found that the particles bounced offthe rod acquired a positive charge. This was a missing link. Without hail and super cooled clouds, he concluded, there could be no lighting.
