Hydrogen gas is liquefied first than helium gas because hydrogen has a higher critical temperature and pressure than helium. This means that hydrogen can be liquefied at higher temperatures and pressures compared to helium. Helium requires lower temperatures and pressures to be liquefied, making it more challenging to achieve compared to hydrogen.

Is hydrogen more dangerous than oxygen Why?
Hydrogen is dangerous than Helium because Hydrogen is a stronger gas than Helium.
What has more mass hydrogen or helium?
Helium has more mass than hydrogen. Helium is composed of two protons and two neutrons, while hydrogen is a single proton.
What type of element is better than helium?
In terms of buoyancy, hydrogen is better than helium because it is lighter. However, hydrogen is flammable, so helium is typically preferred for safety reasons.
What is an element denser than helium?
EVERYTHING except hydrogen is denser than helium.
What is lighter than helium but heavier than air?
hydrogen
Would an hydrogen balloon float better than a helium one?
Hydrogen is lighter than helium. So hydrogen balloon will float better than helium.
Is hydrogen more dangerous than oxygen Why?
Hydrogen is dangerous than Helium because Hydrogen is a stronger gas than Helium.
What has more mass hydrogen or helium?
Helium has more mass than hydrogen. Helium is composed of two protons and two neutrons, while hydrogen is a single proton.
Is hydrogen lighter than helium?
No, helium is almost 4 times as heavy as hydrogen.
Which is lighter - helium or hydrogen?
Helium is lighter than hydrogen. Helium has an atomic number of 2, which means it has two protons and two neutrons in its nucleus, making it lighter than hydrogen, which has only one proton in its nucleus.
What is colder helium or hydrogen?
Helium is colder than hydrogen at the same temperature because helium has a lower boiling point (-268.9 degrees Celsius) compared to hydrogen (-252.9 degrees Celsius).
Which is heavier hydrogen or helium?
Helium is heavier than hydrogen. Hydrogen is the lightest and simplest element in the periodic table, while helium is the second lightest element.
What type of element is better than helium?
In terms of buoyancy, hydrogen is better than helium because it is lighter. However, hydrogen is flammable, so helium is typically preferred for safety reasons.
What is an element denser than helium?
EVERYTHING except hydrogen is denser than helium.
Which has the least number of atoms 5g of hydrogen or 10g of helium?
10g of helium has fewer atoms. This is because the atomic mass of helium is much higher than that of hydrogen, so the same mass of helium contains fewer atoms than the same mass of hydrogen.
Which gas is lighter than helium?
hydrogen
What is helium in relation to hydrogen?
The atomic number of helium is one more than that of hydrogen. In both the elements, the electrons are filled in the 1s orbitals. Hydrogen has one electron, helium has two.
