The gradient (or gradient vector field) of a scalar function f(x 1, x 2, x 3, …, x n) is denoted ∇f or ∇ → f where ∇ denotes the vector differential operator, del. The notation grad f is also commonly used to represent the gradient.
1. a. : the rate of regular or graded (see grade entry 2 sense transitive 2) ascent or descent : inclination. b. : a part sloping upward or downward. 2. : change in the value of a quantity (such as temperature, pressure, or concentration) with change in a given variable and especially per unit distance in a specified direction. 3.
Concentration gradients. Particles move from high to low concentration areas, a process called diffusion. Each particle type has its own unique concentration gradient. This movement isn't planned, but happens randomly. Over time, particles spread evenly, balancing the probability of movement in all directions.

- There is no goal in concentration gradient, this is just an effect of the constant motion that particles have.
- By putting any kind of barrier in the form of something impermeable between molecules. In that case, molecules cannot move.
- Well, the presence of the membrane itself helps to create a concentration gradient. Once you have a barrier it helos creating 2 different compartme...

- it usually doesn't you can check the concentration but this is not likely by a lot
- Yes, diffusion happens, because atoms are always moving (you can feel it as the temperature of something) and because they collide they have very r...
The rate at which a physical quantity, such as temperature or pressure changes over a distance. A operator on scalar fields yielding a vector function, where the value of the vector evaluated at any point indicates the direction and degree of change of the field at that point. Discover More.
gradient, in mathematics, a differential operator applied to a three-dimensional vector-valued function to yield a vector whose three components are the partial derivatives of the function with respect to its three variables. The symbol for gradient is ∇.

Oct 23, 2017 · Scientists Say: Gradient. This is the rate that something — such as elevation, concentration or temperature — changes over a distance or time. Bees follow a gradient of scent molecules to find flowers. A strong scent means they are getting closer.
Feb 24, 2017 · Gradient refers to how steep a line is, which is basically the slope. $\frac{dP}{dx}$ and $\frac{d\theta}{dx}$ are basically the derivative of a function, i.e its slope. The easiest way to determine slope is to graph the function, then observe the x coordinate of a point on the graph and its respective y coordinate.
