What color does an acid and a base turn litmus paper? If the chemical or liquid is a base it will turn the paper blue and if it is an acid it will turn it red Edit
The Gradient. The gradient is a vector operation which operates on a scalar function to produce a vector whose magnitude is the maximum rate of change of the function at the point of the gradient and which is pointed in the direction of that maximum rate of change.In rectangular coordinates the gradient of function f(x,y,z) is:If S is a surface of constant value for the function f(x,y,z) then the gradient on the surface defines a vector which is normal to the surface. ApplicationsConduction heat transfer.f S is a surface of constant value for the function f(x,y,z) then the gradient on the surface defines a vector which is normal to the surface.

Slope / Gradient. The concept of slope is used in various sections of mathematics and worked with quite often when solving and graphing linear equations. The slope or degree of slant of a line is defined as the degree of steepness or incline of the line.radient in Geometry. In geometry, given a line that makes an angle Î¸ with the x-axis, the slope m is defined as. In geometry, the gradients of a lines can be used to determine their relationship i.e. whether the lines are parallel to each other or perpendicular. For example: Given two lines with slopes m1 and m2.
