Correct Answer: Freon


Solution : The correct answer is Freon .

Freon is an odourless, clear, non-corrosive gas, and due to its lower surface tension and boiling point, it becomes easily usable as a refrigerant. Freon is used in refrigerators to absorb the heat from the inside chamber and exhaust it outside. The refrigerator pumps out the heat from the inside to the outside using a heat pump.
