The rate of diffusion in solids is very low for a few reasons. The particles are very tightly kept in bound positions. They are not free to move around.

What phase of matter are most elements when they are at a very low temperature?
Most elements are solids when they are at very low temperatures.
Why do solids lack the property of diffusion?
Because diffusion involves the random movement of particles. In a solid, particles cannot move to an area of low concentration as the intermolecular forces are too great. So the particles stay tightly packed in a solid.
What is it called when particles travel from an area of high concentration to an aera of low concentration?
Through passive transport
Why is rate of diffusion different in liquids and gases?
a solid is the state of matter in which the molecules are closely packed with each other and is rigid where as gas is the states of matter in which the molecules are loosely packed and is freely movable.
Why does the minimum in a plot of plate height vs flow rate occur at lower rates with liquid chromatography than with gas chromatography?
Longitudinal diffusion is much more important in GC that in LC. Longitudinal diffusion is a large contribution to H at low flow rates. The initial decreases in H in plots of plate height vs. flow rate are thus largely the result of longitudinal diffusion.. Because gaseous diffusion coefficients are orders of magnitude larger than liquid values, the phenomenon becomes noticeable at higher flow rates in GC than in LC. The minimum is sometimes not observed at all in LC.
Does air have a very low density?
Compared to liquids and solids, yes a very low density.
What phase of matter are most elements when they are at a very low temperature?
Most elements are solids when they are at very low temperatures.
What are the crime rates in Sweden?
Very low
Do any instant credit cards offer low interest rates?
The instant credit cards to not have very low rates on them as that is how they make their money. Try using a Visa to get low rates.
Why cant beta particles penetrate very far into solids?
They have low velocity
Do ionic solids have low melting points?
No, ionic solids have very high melting points. Ionic solids are one of the strongest bonds formed among elements.
Why do solids lack the property of diffusion?

Why do solids have a low heat capacity?
Their particles are very organized and packed together!! Lol
The spreading out of a substance from an area of high concentration to an area of low concentration is called .?
diffusion
The movement of particles from a high concentration to a low concentration?
diffusion
What is it called when particles travel from an area of high concentration to an aera of low concentration?
Through passive transport
Are current home mortgage rates lower?
In the current economy, home mortgages rates are a lot lower and easier to maintain. With the current economy and low mortgage rates it is also to purchase foreclosed homes at a very low price.
