Why hydrogen and helium does not satisfy joule Thomson effect?
Wiki User
∙ 11y ago
As the gs flow from high pressure to low pressur using the porus plug the temperature of the gas increases as the pressure of the gas decreases.
As we know in all this process the enthalpy is constant . So, to stay it constant the internal energy increases which lead to increase in temperature of the gas.
Formula h=u+pv
h--- enthalpy
u-- internal energy
p--pressure
v---volume

Why does a helium tank get colder as you let out more helium?
Letting gas out of a cylinder always causes a cooling. This is the Joule-Thomson effect. As the gas expands work is done against the interatomic/molecular attractions (dispersion forces for helium).
When are hydrogen and helium form?
Hydrogen and helium are formed in Sun.
What occurs when Hydrogen is turned into helium?
The result of this separation will be pure hydrogen and pure helium.
How much hydrogen and helium is on Saturn?
About 96% hydrogen and 2% helium.
Does hydrogen combine with helium?
No. helium does not react with any element.
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 are the two main elements found in the stars?
Hydrogen and helium
What are the symbols for hydrogen and helium?
The chemical symbol for helium is "He."

Hydrogen and helium formulas?
Hydrogen is H2. Helium is He.
The two elements most abundant in the universe are?
Hydrogen and helium are the two most abundant elements in the universe.
Which is lighter - helium or hydrogen?
Hydrogen is lighter than Helium.
Does helium have hydrogen in it?
No. Helium and Hydrogen are two different elements.
When are hydrogen and helium form?
Hydrogen and helium are formed in Sun.
The sun is composed of what?
mostly hydrogen and helium
What are the Sun's main atmospheric gases?
Hydrogen and helium. Mostly hydrogen.
Is hydrogen lighter than helium?
No, helium is almost 4 times as heavy as hydrogen.
