How does volume affect rms speed?
Since the temperature is remaining constant, the average kinetic energy and the rms speed remain the same as well. The volume of the container has decreased, which means that the gas molecules have to move a shorter distance to have a collision.
What is the rms speed?
The root-mean-square speed is the measure of the speed of particles in a gas, defined as the square root of the average velocity-squared of the molecules in a gas. The root-mean-square speed takes into account both molecular weight and temperature, two factors that directly affect the kinetic energy of a material.
Does hydrogen diffuse faster than helium?
Graham’s law of diffusion states that the rate of diffusion is INVERSELY proportional to the square root of the molecular masses of each gas…. And thus dihydrogen will diffuse approx. 1.4 times faster than the more massive helium….
Which gas from each set will have the highest rate of effusion through a pinhole?
Hydrogen gas
Which type of diffusion is very very slow?
The diffusion of a solid in another solid is a very slow process because the particles in solids can not move from their positions. the particles can show a little vibrations about their fixed position. due to lack of sufficient movements in particles of solids,the diffusion of solids in solids is a slow process.
Why is diffusion slow in solid?
Diffusion is a slow process in solids because the particles do not move from their fixed positions and only vibrate.
What factors does not affect the rate of diffusion?
The factor that does not affect the rate of diffusion are the electrical charges of the diffusion particles. The electrical charges do not participate in such processes.
What factors speed up diffusion?
The rate of diffusion
| Factor | How the factor affects the rate of diffusion |
|---|---|
| Concentration gradient | The greater the difference in concentration, the quicker the rate of diffusion |
| Temperature | The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly |
