.A copper-constantan thermocouple is used between S 1 and S 2 .When sun's rays fall on S 1 , its temperature rises. The temperature of the junction (of the thermocouple) near S 1 increases. The galvanometer gives deflection. Now, current is passed through S 2 , so that temperature of S 2 becomes eq..

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

The hydrolysis constant may be written as: ..

A function f : A g B is said to be a constant function, if ..

The amount of solar energy received per second by one square metre of the near earth space (exposed perpendicularly to the rays of the sun) at an average distance between the sun and the earth is called solar constant. Solar constant = 1.4 kW/m 2 Black Surfaces Absorb More H..

The hydrolysis constant may be written as: (vi) for weak acid, For weak base BOH, Also, K w = [H + ] [OH - ] Multiplying equation (vi) by equation [H + ] [OH - ], we get ..

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 b..

In mathematical sense, equilibrium constant is not a constant. It is called constant because at a fixed temperature and pressure, the value of the equilibrium constant for a reaction is constant. The unit of equilibrium constant (K) ..

From the above ideal gas equation: ..

The value of the equilibrium constant of a reaction is the same, at constant 'T' and 'P'. However, if either temperature 'T' or pressure 'P' or both are changed, the value of the equilibrium constant may also change. For example, the value of K p (equilibrium co..
