What is concerntration gradient?
As used in the process of diffusion, the concentration gradient is the graduated difference in concentration of a solute within a solution (as expressed per a unit distance). Molecules tend to move from areas of greater concentration to areas of lesser concentration. i.e. down the gradient.
Rate of diffusion is dependent upon molecular?
size, temperature, and concentration gradient. Smaller molecules diffuse faster than larger molecules, as they can more easily navigate through the spaces between other molecules. Higher temperatures increase the kinetic energy of the molecules, leading to faster diffusion. A steeper concentration gradient, where there is a large difference in concentration between two areas, also promotes faster diffusion.
What is Fick's law?
Ficks laws (note that there are two of them) are:Most people are concerned with Fick's first law which relates the diffusive flux to the concentration under the assumption of steady state:R=D X A Dp / dR=the rate of diffusionD=diffusion coefficient, which is a characteristic of the medium and varies exponentially with temperatureA=the surface areaand dC/dx Is the concentration gradient over the diffusion distanceFick's first law suggests that the rate of diffusion in a given direction across and exchange surface:1. is directly proportional to the concentration gradient- the steeper the concentration gradient, the faster the rate of diffusion2. is directly proportional to the surface area- the greater the surface area of a membrane through which diffusion is taking place, the faster the rate of diffusion this is one of the factors which limits cellsize.3. is inversely proportional to the distance- the rate of diffusion decreases rapidly with distance. diffusion is thus effective only over short distances. this limits cell size.Fick's second law predicts how diffusion causes the concentration to change with time. It is a partial differential equation which, within the character limitations of Wikianswers, the second law is:δφ/δt = ▼·(D▼φ)whereδ is being used as the symbol for partial differentialφ is the concentration in dimensions of [(amount of substance) length−3]t is time· is the "dot product"▼ is the del or gradient operatorD is is the diffusion coefficient in dimensions of [length2 time−1]Note that when φ is at steady state, this equation reduces to Fick's first law.
Does a middle latitude cyclone have a steeper pressure gradient than a tornado?
No. A tornado produces the steepest pressure gradient of any weather phenomenon. An intense mid-latitude cyclone might have an overall pressure deficit comparable to a weak tornado, but that pressure gradient is spread out over several hundred miles. A tornado produces at least that much of a pressure drop over only a few hundred feet.
What is the meaning of a steeper line on a distance v. time graph?
The slope will tell you how much change of Y to X >.
Diffusion can be accelerated by?
Increasing the temperature, lighter particles, higher surface area to volume ratio and a steeper concentration gradient.

Which affects the rate of diffusion through a semipermeable membrane?
steeper concentration gradients, higher temperatures and size of the molecule diffusing
How does a gradient affect the steepness of the line?
The higher the gradient, the more steeper the line will be.
How does a streams gradient affect of velocity?
The steeper the gradient, the higher the velocity of flow.
Which affects the rate of diffusion through a semipermeable membrane steeper concentration of gradients higher temperatures or the size of the molecule diffusing?
all of thouse factors
The closer the isobars are together?
the steeper the pressure gradient

How does the gradient of river affect it flow?
The gradient of a stream affects the speed of the water as it moves downstream. The steeper the gradient, the faster the water moves.
How does a rivers gradient affect its speed erosion capabilities?
The steeper a river's gradient, the faster and greater the erosive power is.
Is 1.08 a steeper gradient than 45?
Yes. 1.08 is about 47.2 degrees.
