Question

A chemical used in refrigerator and air conditioners a source of Chlorine is ___________
A. Benzene
B. $C{H_4}$
C. Benzopyrene
D. Freon

Answer 1

Hint: The fluid or gaseous compound which is capable of absorbing heat from the environment to produce a cooling process via refrigerator and the air conditioner is known as refrigerant. There are three types of refrigerants are found, named chlorofluorocarbons, hydrofluorocarbons, and hydrochlorofluorocarbons.

Complete answer:
Freon is a non-flammable aliphatic gas which is used in refrigerators and air conditioner as the source of Chlorine.
Freon is a lower toxic gas which is also used as aerosol propellant.
In the case of air, the conditioner freon is located inside the copper coil of the air conditioner. Freon absorbs heat from the inside the room. After absorption of heat freon is transferred from to high-pressure liquid from low-pressure gas. Then the component of the air conditioner transfers the frontside over the blowing fan.
The refrigerator pumps out the heat from inside to outside by heat pump. Freon is used in the refrigerator to absorb heat from the inside to exhaust outside.

So, the correct answer is option D.

Additional note: Both chlorofluorocarbon and hydrochlorofluorocarbons are responsible for producing greenhouse gases and damage the ozone layer. Hydrofluorocarbons are much safer than chlorofluorocarbon and hydrochlorofluorocarbons.

Note: Freon is odorless clear non-corrosive gas. Due to lower surface tension and boiling point, it is easily usable for the refrigerant. The major freon gases which are used in the air conditioner and refrigerator are freon11, freon 12, freon 114, freon22, etc.
