The average speed of helium particles in a room is greater than that of nitrogen molecules primarily due to their lighter molecular mass. According to the kinetic molecular theory, at a given temperature, lighter gases move faster than heavier gases because they have higher average kinetic energy. Helium, with a molecular weight of about 4 g/mol, is significantly lighter than nitrogen, which has a molecular weight of about 28 g/mol. As a result, helium particles will have a higher average speed compared to nitrogen molecules under the same conditions.
A balloon is primarily filled with air, which consists of a mixture of gases, predominantly nitrogen and oxygen molecules. These gas molecules are made up of atoms, specifically nitrogen (N2) and oxygen (O2) particles. When inflated, the balloon contains these gas particles that move freely, creating pressure against the balloon's inner walls. Additionally, if the balloon is filled with helium, it contains helium atoms (He) instead of air molecules.
Helium molecules are lighter than most air molecules in the atmosphere (mostly nitrogen and oxygen) therefore they are prone to rise while heavier molecules move downward.
Helium is the lightest of the three gases, with an atomic mass of 4 compared to 16 for oxygen and 14 for nitrogen.
The air molecules slow down and it deflates.
The particles of helium are farthest apart in a balloon.

Helium has smaller particles than nitrogen or oxygen. Helium atoms are smaller in size, as they have fewer protons and neutrons in their nucleus compared to nitrogen or oxygen atoms. This smaller size allows helium atoms to move more freely and escape into the atmosphere, which is why helium is a lighter gas.
oxygen,helium,carbon dioxide,nitrogen
The rate of effusion of helium (He) is typically faster than that of sulfur dioxide (SO2) because helium has a lower molar mass, which makes its gas particles move faster on average. This means that helium molecules can escape through a small opening more rapidly than sulfur dioxide molecules.
nitrogen is an atom, it isn't made up of atoms, though all elements are made up of hydrogen and helium
Um... because the helium was insufficiently purified? There is no nitrogen in pure helium.
The chemical formula for helium is He, while the chemical formula for nitrogen is Nā.
yes helium and nitrogen are hot gases
If you pour liquid helium into liquid nitrogen, the helium will not mix with the nitrogen and will instead form separate layers. Helium is lighter than nitrogen and has a lower boiling point, so the helium will tend to float on top of the nitrogen.
Nitrogen is the heavier gas (mass of 28) compared to helium (mass of 4).
At the same temperature and prssure in a gas the helium atoms will on average move faster than the O2 molecules.
Nitrogen and helium have different properties. Nitrogen is a gas at room temperature, while helium is a gas at very low temperatures. Nitrogen is a common element in the Earth's atmosphere, while helium is much rarer. Nitrogen is essential for life, while helium is mostly used for balloons and as a coolant in certain applications.
