Which gas effuses faster at the same temperature molecular oxygen or atomic argon?

Which factors does molecular speed depend on?
Molecular speed depends on temperature, molecular mass/weight, and the medium in which the molecules are moving. An increase in temperature generally increases molecular speed, while higher molecular mass tends to decrease speed. Additionally, molecules tend to move faster in lighter or less dense media.
Why does the coefficient of viscosity of liquids increase with an increase in temperature?
Temperature measures the speed of random thermal motion on the atomic and molecular level. When sub-microscopic particles are moving faster, the liquid as a whole will be more fluid and less viscous.
What is the definition of Graham's law of diffusion?
This law relates the rate at which a gas diffuses or effuses to the type of molecule in the gas. This rate of diffusion of a gas is inversely proportional to the square root of it's molecular mass.
What is a measure of the speed of molecules?
The measure of the average speed of molecules in a substance is known as temperature. Temperature is a reflection of the kinetic energy of molecules, with higher temperatures indicating faster molecular movement.
What measures heat and cold?
A thermometer measures heat or cold by detecting the temperature of an object or the surrounding environment. Heat causes the molecules to move faster, increasing the temperature, while cold slows down molecular movement, lowering the temperature.
Does changing the temperature affect the rate of osmosis?
Certainly; molecules move faster at a higher temperature (that is what temperature is, at a molecular level) and therefore undergo osmosis faster as well, since that is a form of molecular motion.
A physical property that tells you how hot or cold matter is?
The physical property that tells you how hot or cold matter is, we call temperature. Temperature consists of random motion on the atomic or molecular scale. Faster moving particles have higher temperatures.
Does nitrogen or iodine effuse faster?
Nitrogen will effuse faster, since it has a smaller molar mass than iodine. Hope this helped!
Which gas effuses the fastest bromine or chlorine or ammonia or Hydrogen?
Hydrogen would effuse the fastest because it has the lowest molar mass among the gases mentioned. Effusion rate is inversely proportional to the square root of molar mass, so lighter gases effuse faster.
How fast does hydrogen effuse?
Rms= sqrt(((3)(8.314)(273.15k))/(1g/mole)) = 82.54 is the speed of one hydrogen molecule. Assuming stp
How much faster does UF 235 effuse compared with UF 238?
Uranium-235 (UF₃₅) effuses faster than uranium-238 (UF₂₃₈) because of its lower molecular weight. According to Graham's law of effusion, the rate of effusion is inversely proportional to the square root of the molar mass. Since UF₃₅ has a molar mass of approximately 235 g/mol and UF₂₃₈ has a molar mass of about 238 g/mol, UF₃₅ effuses roughly 1.01 times faster than UF₂₃₈.
What gas effuses four times as fast as oxygen?
Helium is a gas that effuses four times faster than oxygen. This is because helium has a lower molar mass compared to oxygen, leading to faster effusion rates as per Graham's law of effusion.
Is molecular movement directly related of inversely related to temperature?
Molecular movement is directly related to temperature. As temperature increase, the additional energy is absorbed by the molecules. This energy is converted to motion energy and the molecules will move faster.
What is the speed at which molecules or atoms move dependent on temperature and state of matter?
The speed at which molecules or atoms move is dependent on temperature and state of matter. In general, higher temperatures result in faster molecular or atomic movement, while different states of matter (solid, liquid, gas) have different average speeds of molecular motion due to differences in intermolecular forces.
Why do solids becomes more soluble in water as the temperature increases?
Temperature is a measurement of the average kinetic energy on the atomic or molecular level; hotter substances have faster moving particles. Faster moving particles have more energetic collisions with the particles of which solids are formed, which are more able to knock them out of the solid and into the solution, than slower moving particles would be.
What does heat result from?
Heat is random motion or vibrations that take place on an atomic or molecular level. The faster particles are moving, the hotter they are.
Which factors does molecular speed depend on?
Molecular speed depends on temperature, molecular mass/weight, and the medium in which the molecules are moving. An increase in temperature generally increases molecular speed, while higher molecular mass tends to decrease speed. Additionally, molecules tend to move faster in lighter or less dense media.
