Question

A chemical used in refrigerators and air conditioners and is a source of $${Cl}^{-}$$ is
A)Benzene
B)${CH}_4$
C)Benzopyrene
D)Freon

Answer 1

Hint: The fluid or gaseous compound which is capable of absorbing warmth from the surroundings to produce a cooling manner with the aid of a fridge and the air conditioner is known as refrigerant. There are three kinds of refrigerants are found, named chlorofluorocarbons, hydrofluorocarbons, and hydrochlorofluorocarbons.

Complete answer:
Freon is a non-flammable aliphatic gasoline which is used in refrigerators and air conditioners as the supply of Chlorine. Freon is a lower toxic gasoline 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 warmth from the inside of the room. After absorption of warmth freon is transferred from to high- stress liquid from low-pressure gas. Then the component of the air conditioner transfers the front side over the blowing fan. The fridge pumps out the warmth from inside to the backyard by using a warmth pump. Freon is used in the fridge to absorb warmness from the interior to exhaust outside.

Both chlorofluorocarbon and hydro chlorofluorocarbons are responsible for producing greenhouse gases and harm the ozone layer. Hydrofluorocarbons are tons safer than chlorofluorocarbons and hydrochlorofluorocarbons.

Hence, the correct answer is option (D)

Note: Freon is odourless clear non-corrosive gas. Due to decreased surface tension and boiling point, it is effortlessly usable for the refrigerant. The predominant Freon gases which are used in the air conditioner and fridge are freon11, Freon 12, Freon 114, freon22, etc.
