Answer to Question 1

ANSWER: The word smog originally meant the combining of smoke and fog. Today, however, the word mainly refers to the type of smog that forms in large cities, such as Los Angeles. Because this type of smog forms when chemical reactions take place in the presence of sunlight (called photochemical reactions), it is termed photochemical smog, or Los Angelestype smog. When the smog is composed of sulfurous smoke and foggy air, it is usually called London-type smog.

Answer to Question 2

ANSWER: Volatile organic compounds (VOCs) represent a class of organic compounds that are mainly hydrocarbons individual organic compounds composed of hydrogen and carbon. At room temperature they occur as solids, liquids, and gases. Although thousands of such compounds are known to exist, methane (which occurs naturally and poses no known dangers to health) is the most abundant. Other volatile organic compounds include benzene, formaldehyde, and some chlorofluorocarbons .
