(Question)
Answer the following question given this paragraph: A neon light produces visible light by electroluminescence. In this process, neon or some other gas gives off light when an electric current passes through it. Other halogen gases besides neonincluding krypton and argonalso produce light in this way. The word "OPEN" in the sign below is a neon light. It is a long glass tube that contains neon gas. When electricity passes through the gas, it excites electrons of neon atoms, and the electrons jump to a higher energy level. As the excited electrons return to their original energy level, they give off visible light. Neon produces red light. Other gases produce light of different colors. For example, krypton produces violet light, and argon produces blue light. Q: Neon, krypton and argon are examples of what kind of gases, which produce light by electroluminescence? Choices: - radiation gases - ionic gases - irradiation gases - halogen gases A:
(Answer)
halogen gases

Ques: Answer the following question given this paragraph: The depression that allows water to collect to form a lake may come about in a variety of ways. The Great Lakes, for example, are glacial lakes. A glacial lake forms when a glacier scrapes a large hole in the ground. When the glacier melts, the water fills the hole and forms a lake. A kettle lake forms in the sediment left by a glacier when a block of ice melts. Kettle lakes are found where continental glaciers once covered the land ( Figure ' below ). Over time lakes get water from rain, streams, and groundwater coming to the surface. Q: What forms when a glacier scrapes a large hole in the ground? Choices: - crater lake - underground cavern - glacial hill - glacial lake A:
Ans:
glacial lake
