Because the liquid-to-gas expansion ratio of nitrogen is 1:694 at 20 °C (68 °F), a tremendous amount of force can be generated if liquid nitrogen is vaporized in an enclosed space. In an incident on January 12, 2006 at Texas A&M University , the pressure-relief devices of a tank of liquid nitrogen were malfunctioning and later sealed.

Graphite flakes can cost around US$0.9/kg carbon. [20] Price of synthetic industrial diamond for grinding and polishing can range from 1200 to 13 300 USD/kg, while cost per weight of large synthetic diamonds for industrial applications can be on the order of million dollars per kilogram. [21] 7: N: Nitrogen: 0.0012506: 19 (5.263 × 10 17 kg) 0. ...
Although the liquid nitrogen is colder than the ambient temperature, the liquid nitrogen engine is nevertheless an example of a heat engine.A heat engine runs by extracting thermal energy from the temperature difference between a hot and a cold reservoir; in the case of the liquid nitrogen engine, the "hot" reservoir is the air in the ambient ("room temperature") surroundings, which is used to ...
Aircraft & motor vehicle tires: Although air is 78% nitrogen, most aircraft tires are filled with pure nitrogen. There are many tire and automotive shops with nitrogen generators to fill tires. The advantage of using nitrogen is that the tank is dry. Often a compressed air tank will have water in it that comes from atmospheric water vapor ...
Cost: $8.393. Paying over $8 per gallon for gas may seem horrible, but last summer, Norwegians faced costs of over $10 per gallon. Despite the recent price drop, in Norway gas still costs more ...
For liquid nitrogen L, the heat of vaporisation is 200kJ/Kg; The boiling point of liquid nitrogen is 77Kelvin; The temperature of atmospheric air is ~ 300Kelvin; And this gives 570 kilojoules of energy per kg of Liquid nitrogen Lumos3 15:47, 18 July 2005 (UTC) Yep, and the energy density of gasoline is 45,000 kJ/kg.
The average cost of gas has decreased 15% in the last two years, from when it was $4.27 per gallon. The highest recorded average price of regular gas was in June 2022 at $5.06 per gallon.
