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.

This shows the pressure of the gas is directly proportional to the absolute temperature of the gas. Doubling the temperature will double the pressure for a fixed mass of gas at constant volume. The gradient of the slope is the constant in Charlesâ Law. It also shows that if the gas is cooled to absolute zero then the energy of the molecules is at the lowest energy state and therefore cannot generate any pressure.
