boltzmann constant planck constant

E.g., gravitational constant (G), Planck's constant (h) and velocity of light (c) Their values are always constant..

The energy of thermal radiation emitted per unit time by a black body of surface A, is given by u = s AT 2 -----(1) where s is a universal constant known as Stefan-Boltzmann constant and T is its temperature on absolute scale. The measured value of s is 5.67 x 10 - 8 W..

If the same error is repeated every time in a series of observations, the error is said to be constant error. Constant error is due to faulty calibration of the scale of a measuring instrument. In order to minimise the constant error, measurements are made with all po..

The hydrolysis constant may be written as: The hydrolysis constant 'K h ', of the salt is inversely proportional to the dissociation constant, 'K b ' of the weak b..

Let f(x) = k be the given function. Then, we have Therefore derivative of a constant is 0. or..

A function f : A B Such that A, B R, is said to be a constant function if there exist K B such that f(x) = k. Domain = A Range = {k} The graph of this function is a line or line segment parallel to x-axis. Note that, if k>0, the graph B is above X-axis. If k<0, the graph i..

Relationship between Critical Constant and Van der Waal's Constants - The relationship between critical constants of the gases and their Van der Waal constants is as follows: (i) V c = 3b (ii) P c = a/27b 2 (iii) T c = 8a/27Rb (iv) The critical compressibilit..

The relationship between critical constants of the gases and their Van der Waal constants is as follows: (i) V c = 3b (ii) P c = a/27b 2 (iii) T c = 8a/27Rb (iv) The critical compressibility factor Z c is given by, ..

Identify the constant function from the graphs. => Graph 1 or Graph 3 or Graph 2 or Graph 4..

Here, the velocity-time graph is a straight line with a negative slope, as shown in the figure below...
