Chapter 1.1, Problem 6SSC

Interpretation Introduction

Interpretation:

The reason of increase of chlorofluorocarbons in the atmosphere needs to be explained.

Concept introduction:

A substance is a matter which has distinct properties and distinct composition. Iron, sodium bicarbonate (baking soda), sucrose (pure sugar), sodium chloride (table salt), sulfur, tin, diamond, etc. are the examples of substances.

Answer to Problem 6SSC

CFCs are anthropogenic compounds. It is used as an alternative of refrigerants. People or an individual used them (appliances that contain CFCs) as coolant, and scientists did not imagine that it will affect the atmosphere of the Earth.

Explanation of Solution

Chlorofluorocarbons are anthropogenic compounds. CFCs were developed (or formed) as a safe choice to ammonia, a popular refrigerant. CFCs were developed (or formed) by industrial chemists. It’s a human made chemical.

A lifetime of CFCs in the atmosphere is about 20-100 years. One free atom of chlorine from a molecule of CFC can cause so damage (or harmful). The above-mentioned may destroy ozone molecules (O) for a long period.

An excessive use of freezers, refrigerators, and AC are the main reasons of chlorofluorocarbons increment in the atmosphere. Because these appliances contain fluorocarbons, and various fluorocarbon compounds comprise chlorine. Thus, it increases CFCs in the atmosphere.

Conclusion

An excessive use of refrigerantsmay increase CFCs in the atmosphere.
