उत्तर
- Ammonia is environmentally compatible. It does not deplete the ozone layer and does not contribute towards global warming.
- It has superior thermodynamic qualities; as a result, ammonia refrigeration systems use less electricity.
- Ammonia has a recognizable odour and so leaks are not likely to escape. It being lighter than air goes up in the atmosphere, not affecting life too much on earth.
