<h2 id='frequently-asked-questions'>Frequently Asked Questions</h2>

1. **What makes nitrogen gas inert?**
   - Nitrogen gas (N2) has a strong triple bond in its molecules, making it chemically stable and non-reactive under normal conditions.

2. **Where is nitrogen gas sourced from?**
   - Nitrogen gas is primarily obtained through the fractional distillation of liquid air, an energy-intensive process.

3. **Why is nitrogen used in tire inflation?**
   - Nitrogen is used to inflate tires because it maintains pressure better than regular air, reducing the risk of tire blowouts and extending tire life.

4. **How does nitrogen preserve food?**
   - By displacing oxygen, nitrogen prevents oxidation and spoilage, maintaining the quality and extending the shelf life of perishable products.

5. **Is nitrogen gas safe for human contact?**
   - While non-toxic, nitrogen can displace oxygen in enclosed spaces, posing asphyxiation risks if not properly ventilated.
