Answer:
Tire inflation and in spray cans, such as aerosol paint cans or suncream sprays.
Step-by-step explanation:
One use of nitrogen gas is to inflate car or plane tires. Nitrogen is better than air for the tires because, as it is an inert gas, it does not react with other components as Oxygen does, making nitrogen a safer gas for the tires.
Another use of nitrogen gas is in aerosol paint cans. As it is an inert gas, it is in spray paint cans, shaving cream, suncream spay, amongst other sprays, to work as a gas that will push the paint out of the container. In other words, different industries use nitrogen gas as propellant gas.
