This means that they would not be able to provide the necessary cushioning or protection for items being shipped. Additionally, CFCs are flammable, so they would be a safety hazard if used in packing material.<\/p>\n<p>A refrigerator is a household appliance that is used to keep food cold. Refrigerators typically use CFCs as a refrigerant, which is a substance that absorbs heat from the inside of the refrigerator and releases it to the outside. This process helps to keep the food inside the refrigerator cold.<\/p>\n<p>An air conditioner is a device that is used to cool a room or building. Air conditioners typically use CFCs as a refrigerant, which is a substance that absorbs heat from the air and releases it to the outside. This process helps to cool the air inside the room or building.<\/p>\n<p>A mixer and grinder is a kitchen appliance that is used to mix and grind food. Mixers and grinders typically do not use CFCs, as there are other, safer substances that can be used for these purposes.<\/p>\n<p>In conclusion, the correct answer to the question &#8220;Chlorofluorocarbon are not used in . . . . . . . .&#8221; is D.
