2 Answers
Here are two applications for each of the following gases:
### (i) **Nitrogen (N₂)**
1. **Inert Atmosphere in Industrial Processes**: Nitrogen is used to create an inert atmosphere for processes like welding and soldering, where reactive gases (like oxygen) can cause unwanted reactions.
2. **Food Preservation**: Nitrogen is used in food packaging to replace oxygen, thereby preventing oxidation, which can lead to spoilage of food items.
### (ii) **Hydrogen (H₂)**
1. **Fuel Cells**: Hydrogen is a clean energy source used in fuel cells to produce electricity, with water as the only byproduct.
2. **Hydrogenation of Oils**: In the food industry, hydrogen is used to convert unsaturated fats into saturated fats, producing semi-solid oils like margarine.
### (iii) **Sulfur Hexafluoride (SF₆)**
1. **Electrical Insulation**: SF₆ is used as an insulating gas in high-voltage circuit breakers, switchgear, and other electrical equipment due to its excellent dielectric properties.
2. **Tracer Gas for Leak Detection**: SF₆ is used to detect leaks in various systems, such as underground pipelines, because it is non-toxic and detectable in very small concentrations.
### (iv) **Air**
1. **Combustion**: Air, containing oxygen, is essential for combustion in internal combustion engines, furnaces, and other systems that rely on burning fuel.
2. **Respiration in Medical Systems**: Compressed air is used in medical applications like ventilators and anesthesia machines to support breathing and deliver medications.
These gases play crucial roles in various industries, thanks to their unique properties.

2. **Hydrogen (H₂):**
- **Fuel Cells:** Hydrogen is used in fuel cells to generate electricity through electrochemical reactions, providing a clean and efficient energy source for vehicles and other applications.
- **Hydrogenation:** Hydrogen is used in the hydrogenation process to convert unsaturated fats and oils into saturated fats, which is common in the production of margarine and other food products.
3. **Sulfur Hexafluoride (SF₆):**
- **Electrical Insulation:** SF₆ is used as an insulating gas in high-voltage electrical equipment, such as circuit breakers and switchgear, due to its excellent insulating properties.
- **Magnetic Resonance Imaging (MRI):** SF₆ is used in MRI equipment to maintain the low temperature required for superconducting magnets.
4. **Air:**
- **Respiration:** Air is essential for respiration in living organisms, providing oxygen needed for cellular metabolism.
- **Pneumatic Systems:** Air is used in pneumatic systems to transmit power in various machinery and tools, such as drills, pumps, and conveyors.
