Why do hydrogen and helium get having very low temperatures warmed up instead of cooling in joule-thomson method?
There is for every gas a point called the inversion temperature. Above this temperature, the gas exhibits a reverse Joule-Thompson effect and warms on expansion instead of cooling. The inversion temperatures for hydrogen and helium are quite low compared to those of most other gases.
What else can I help you with?
Does hydrogen support burning?
Hydrogen does not support burning, instead it completely burns.
Would it be true to say that When magma cools underground evaporation results?
No, it would not be accurate to say that evaporation results from the cooling of magma underground. When magma cools, it solidifies into igneous rock rather than evaporating. Evaporation typically occurs when liquids turn into gases at higher temperatures, which is not the case for cooling magma. Instead, the process involves crystallization as minerals form from the cooling magma.
Do hydrogen bonds form more quickly in higher temperatures?
Yes, hydrogen bonds form more quickly in higher temperatures because the increased thermal energy causes molecules to move faster and collide more frequently, allowing hydrogen bonding interactions to occur more rapidly.
What is summer cooling affect?
The summer cooling effect is when the summer cools an area down instead of making it hot.
Water that contains hydrogen 2 atoms instead of hydrogen 1 atoms is called?
Water that contains hydrogen-2 instead of hydrogen-1 is called heavy water.
How come fusion needs hydrogen instead of other elements?
Hydrogen is the simplest and lightest element, which makes it easier for fusion reactions to occur at high temperatures and pressures. Additionally, hydrogen has a single proton in its nucleus, making it more likely to overcome the electrostatic repulsion between positively charged nuclei during fusion. Other elements have larger nuclei with more protons, requiring higher temperatures and pressures to initiate fusion.
Can you live with hydrogen and oxygen instead of H2O?
No, you would need energy to combine hydrogen and oxygen into H2O
Is the oxygen sufficient for burning of hydrogen on the sun?
No. The hydrogen on the Sun does not burn; it fuses to make helium instead.
What happens to a car engine in freezing temperatures when there's no antifreeze?
If you have water instead of antifreeze in your cooling system, it will freeze! You won't be able to start the car, because the engine is connected to the water pump (which won't be able to move). If you have nothing in your cooling system (no water, no antifreeze, nothing else), then you need your head checked. Your car won't start either.
Helium is used in balloons instead of hydrogen because it is?
Helium is used in balloons instead of hydrogen because it is non-flammable. Hydrogen is flammable and can be dangerous, while helium is inert and poses less of a fire risk. Additionally, helium is less dense than air, providing better lift for balloons.
Is Uranus terrestrial?
No, it is made of gases (hydrogen) instead of rocks.
Why does water expand instead of increaing?
due to hydrogen bond
