Hydrogen atoms have a greater velocity than oxygen atoms when both elements are submitted to identical conditions of temperature and pressure. For your results to be exact, there must be an identical number of moles for each type of atom (e.g. 3 mol of H2 and 3 mol of O2).
The oxygen atoms would move faster. They would need a higher kinetic energy value to impart the same energy through collision and be felt as heat
Because the mass of oxygen is more than that of hydrogen.
A hot gas has more thermal energy so the average molecular speed of a hot gas would be higher than a cold gas
no - hydrogen is much lighter and thus faster
Hydrogen - they are smaller

When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules. When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules.
Gas...The molecules are less tightly packed together like in a solid and liquid so they're free to move. They seem more energized, they're faster.
They move slower because in a solid the molecule move faster and in a gas they move slower, therefore, they will move slower. :)
And farther apart, and it changes phase: ice to water, water to gas,
Both are fluids.Gas is compressible whereas liquid is incompressible. The molecules in liquids are loosely attached while in gas the aren't attached at all. The kinetic energy of gas molecules is more than that of liquids.
Like all molecules, a molecule of H20 is in constant motion; 'hot' molecules move faster than 'cold' molecules. If the molecules move slowly enough the substance appears stationary to us (frozen water) and if they move quickly enough they will expand to fill their container (vapor or gas water.)
gas molecules are less densily packed and hence move faster than liquids
The molecules of a gas move faster at higher temperatures, which therefore speeds up diffusion.
When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules. When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules.
Move a lot faster then liquids and solids.
Yes.
Basically, a solid is quite stationary. It doesn't move very much. Liquids have more energy, meaning that the particles move a lot freer. In a gas the particles are a lot further apart, meaning that they have a LOT more space to move. Solids can be made to move faster if you give it enough energy (ie, heat). The atoms then start vibrating faster, making spaces between the atoms. This is what happens (basically) when you melt something.
Yes, the hotter atoms are, the faster they more.
Gas expands the quickest because gas molecules are farther apart than molecules of other substances. Gas molecules also move faster.
Molecules move faster at higher temps.
When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules. When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules.
no, that is the opposite, molecules will move faster and farther apart when the state changes from liquid to gas
