1. Nitrogen Gas:
Nitrogen gas has a variety of applications, including serving as an inert replacement for air where oxidation is undesirable;
Nitrogen is commonly used during sample preparation procedures for chemical analysis;
Nitrogen tanks are also replacing carbon dioxide as the main power source for paintball guns.Nitrogen can be used as a replacement, or in combination with, carbon dioxide to pressurize kegs of somes, particularly stouts and British ales, due to the smaller bubbles it produces, which makes the dispensed smoother and headier.2. Liquid nitrogen:
