Because hydrogen is lighter that helium
Chat with our AI personalities
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.
Hydrogen is dangerous than Helium because Hydrogen is a stronger gas than Helium.
Helium has more mass than hydrogen. Helium is composed of two protons and two neutrons, while hydrogen is a single proton.
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.
EVERYTHING except hydrogen is denser than helium.

Hydrogen is lighter than helium. So hydrogen balloon will float better than helium.
Hydrogen is dangerous than Helium because Hydrogen is a stronger gas than Helium.
Helium has more mass than hydrogen. Helium is composed of two protons and two neutrons, while hydrogen is a single proton.
No, helium is almost 4 times as heavy as 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.
Hydrogen is about 7 lighter than helium.
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).
Helium is heavier than hydrogen. Hydrogen is the lightest and simplest element in the periodic table, while helium is the second lightest element.
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.
EVERYTHING except hydrogen is denser than 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.
Hydrogen has more lifting power than helium because it is lighter. This means that a given volume of hydrogen can lift more weight than the same volume of helium.
