Which of the following gases is used in refrigerators?

Correct option is A

The Correct Answer is (A)Ammonia

Explanation:

Ammonia is commonly used as a refrigerant in refrigeration systems, particularly in large-scale industrial applications. It has excellent thermodynamic properties, making it an efficient coolant. Ammonia refrigeration is widely used in food processing, cold storage, and large air conditioning systems due to its high energy efficiency and low environmental impact.

Information Booster:

1. Ammonia (NH₃) is a highly effective refrigerant because it has a high latent heat of vaporization, meaning it can absorb and release a lot of heat during phase changes.

2. It is commonly used in industrial refrigeration systems, especially for large-scale cooling in industries like food processing and manufacturing.

3. Ammonia is also eco-friendly because it has zero ozone depletion potential and low global warming potential.

4. Despite its efficiency, ammonia is toxic and must be handled with care, particularly in enclosed environments.

5. Ammonia-based refrigeration systems are more energy-efficient than many other refrigerants.
