Question : The commonly used coolant in refrigerators is
Option 1: Ammonia
Option 2: Nitrogen
Option 3: Freon
Option 4: Oxygen
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.
