Hydrogen, nitrogen, oxygen and chlorine are cheapest by volume at atmospheric pressure. When there is no public data on the element in its pure form, price of a compound is used, per mass of element contained. This implicitly puts the value of compounds' other constituents, and the cost of extraction of the element, at zero.
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.
But imagine if you had $115.6 billion like Bill Gates. You too would probably think a box of frozen pizza rolls cost $22 , and not $8. So, let’s spend Bill Gates ‘ money .
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.
'Wild that we do have billionaires': Bill Gates, worth $100-plus billion, would be happy to 'take away 62% of what I have' — and says the rich in America 'should pay more' in taxes
NEW Cooperative, Inc. in Red Oak notified officials Monday, March 11, that a valve on an aboveground tank storing liquid nitrogen fertilizer was left open all weekend, according to a March 28 news ...
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 ...
The liquid air, which takes up one-thousandth of the volume of the gas, can be kept for a long time in a large vacuum flask at atmospheric pressure. At times of high demand for electricity, the liquid air is pumped at high pressure into a heat exchanger, which acts as a boiler. Air from the atmosphere at ambient temperature, or hot water from ...
