Question

________ is released by refrigerators and air conditioning systems into the atmosphere.

Answer 1

Chlorofluorocarbon($\mathrm{CFC}$):

1. The volatile derivative of Methane, Chlorine, and Fluorine is a Chlorofluorocarbon.
2. Refrigerators, air conditioners, greenhouses, etc. are major contributors of Chlorofluorocarbon($\mathrm{CFC}$) to the atmosphere.

Some effects Chlorofluorocarbon($\mathrm{CFC}$):

1. Rising the sea levels.
2. Dangerous for extinctions of local natural species and their habitat also.
3. Some man-made compounds like Chlorofluorocarbons ($\mathrm{CFCs}$), Hydrochlorofluorocarbons ($\mathrm{HCFCs}$) reduce the width of the atmospheric layer stratosphere.

Therefore, Chlorofluorocarbon$\left(\mathrm{CFC}\right)$ is released by refrigerators and air conditioning systems into the atmosphere.
