Question: Answer the following question given this paragraph: You've probably noticed dew on the grass on a summer morning. Why does dew form? Remember that the land heats up and cools down fairly readily. So when night comes, the land cools. Air that was warm and humid in the daytime also cools over night. As the air cools, it can hold less water vapor. Some of the water vapor condenses on the cool surfaces, such as blades of grass. The temperature at which water vapor condenses is called the dew point . If this temperature is below freezing, ice crystals of frost form instead of dew ( Figure below ). The dew point occurs at 100 percent relative humidity. Can you explain why?. Q: What is the name of the "point" that refers to the temperature at which water vapor condenses? Choices: - melting point - brine point - water point - dew point A:
Answer: dew point

Question: Answer the following question given this paragraph: The only light that people can see is called visible light . It refers to a very narrow range of wavelengths in the electromagnetic spectrum that falls between infrared light and ultraviolet light. Within the visible range, we see light of different wavelengths as different colors of light, from red light, which has the longest wavelength, to violet light, which has the shortest wavelength. You can see the spectrum of colors of visible light in Figure below . When all of the wavelengths are combined, as they are in sunlight, visible light appears white. You can learn more about visible light in the chapter "Visible Light" and at the URL below. Q: Where does visible light fall in between on the electromagnetic spectrum? Choices: - infrared light and specific light - infrared light and gamma ray - radio and infrared - infrared light and ultraviolet light A:
Answer:
infrared light and ultraviolet light
