The energy density of liquid hydrogen is approximately 120 megajoules per kilogram (MJ/kg). This high energy density makes it an attractive fuel for various applications, particularly in aerospace and potential future energy systems. However, its low volumetric energy density, due to hydrogen's gaseous state at room temperature and pressure, poses challenges for storage and transport. Overall, while liquid hydrogen offers significant energy per unit mass, practical considerations are essential for its use.
What else can I help you with?
What is cheaper liquid oxygen or luquid liquid hydrogen?
Liquid oxygen is typically cheaper than liquid hydrogen because oxygen is more readily available and easier to produce. Liquid hydrogen, on the other hand, requires more energy-intensive processes for production and storage, making it more expensive.
Why cant you use liquid hydrogen as fuel?
You can use liquid H2 as fuel. NASA has been doing it since the 1960's. However, the handling and storage of liquid hydrogen is challenging, and may not be within the capability of the average person to safely manage in a personal vehicle. Liquid hydrogen could be a fuel of choice for professionally managed public transit such as busses and trains.
Out of hydrogen water and oxygen which one has the highest density?
Oxygen has a higher density than hydrogen. At room temperature and pressure, oxygen has a density of approximately 1.43 grams per cubic centimeter, while hydrogen has a density of about 0.0899 grams per cubic centimeter.
Which fuel contains the most energy in the least mass hydrogen or methanol?
The question makes no sense - you can't consider two variables at once - energy and mass. Most energy for the same mass - hydrogen.
Is the density of water more than the density of hydrogen sulfide?
It is substantially more when water is a liquid (it weighs 1000 g/cubic dm) as hydrogen sulfide (H2S) is a gas weighing 1.363 g/cubic dm. However, a molecule of hydrogen sulfide weighs more than a molecule of water (H2O).
What liquid has the lightest density?
Hydrogen gas has the lightest density of any liquid.
What liquid has lowest density?
kerosene
Which liquid had the lowest density?
I suppose that this liquid is the liquefied atomic hydrogen at 20 K: 0,07099 g/cm3.
What is cheaper liquid oxygen or luquid liquid hydrogen?
Liquid oxygen is typically cheaper than liquid hydrogen because oxygen is more readily available and easier to produce. Liquid hydrogen, on the other hand, requires more energy-intensive processes for production and storage, making it more expensive.
What element has only one energy level and is part of an essential liquid?
Hydrogen because it has one electron in one energy level and is needed to make water (essential liquid).
Density of Hydrogen?
Gaseous hydrogen has a density of 0.08988 g/cm. Liquid and solid hydrogen have a density of about 0.07 g/ccAt standard temperature and pressure (stp), hydrogen as a gas has density 0.08988 grams per litre. Hydrogen atoms have atomic mass of 1, and diatomic hydrogen molecules have molecular mass of 2. From this we can tell that hydrogen is the lightest (least dense) element in the periodic table.
What happens when you mix liquid hydrogen with liquid oxygen?
When liquid hydrogen and liquid oxygen are mixed together in the correct stoichiometric ratio and ignited, they react exothermically to form water vapor. This reaction releases a large amount of energy, producing intense heat and a loud explosion. The reaction between liquid hydrogen and liquid oxygen is commonly used as a rocket fuel due to its high energy output.
How does liquid turn to gas?
Gas turns to liquid when energy is lost. The density of a gas is much less that the density of a liquid. Thus, when energy is lost and the particles of the gas are able to condense, it becomes a liquid.

What is the density if satun?
Estimated at about 0.7 g/cm3 because of the large amount of hydrogen which, due to temp and pressure is liquid.
What density difference is there with liquid chlorine at different temperatures?
The density of liquid chlorine decreases as the temperature increases. At 0°C, the density of liquid chlorine is around 1.56 g/cm^3, whereas at 100°C, the density decreases to approximately 1.41 g/cm^3. This decrease in density with temperature is due to the expansion of the chlorine molecules as they gain heat energy.
