(The values given below should be treated as approximate, as they vary with different specimens of the same material) SI. No Substance Yong’s modulus (Y) 10 11 dyne cm -2 or 10 10 N m -2 Bulk modulus (K) 10 11 dyne cm -2 or 10 10 N m -2 Rigidi..

The formula for the F test used to test the significance of the multiple correlation coefficient R using n the number of data sets and k the number of independent variables and d.f. N = n - k , d.f. D = n - k - 1 is => R 2 ( n - k ) 1 - R 2 ( n - ..

'. As mentioned before, the rates of reactions increase with temperature; in most cases, the rate doubles for every 10 o rise in temperature. This effect can be represented by the ratio of the rate constants measured at two temperatures, that is T K and (T+10)K. This ratio is ca..

Experimentally, it is found that the rate of a reaction is proportional to the concentrations of the reactants raised to some power, provided that other factors, which also affect the rate of the reaction are kept constant. For e.g., for the hypothetical reaction, the rate of reaction might depend ..

Critical velocity is the velocity of a liquid flow upto which its flow is streamlined and after which its flow becomes turbulent. The critical velocity depends on coefficient of viscosity ' h ', density of the liquid ' r ', and radius of the tube (r). Using the methods of dimensions, one ..

The numerical value of equilibrium constant depends upon the stoichiometry of the chemical equation used in representing the reaction. For example, the reaction can also be expressed as Then, the corresponding equilibrium constants are When the coefficients are doubled, then th..

m B n is then expressed as, K s p = [A p + ( a q ) ] m + [ B q - ( a q ) ] n . Thus, the solubility product constant (K s p ) of a sparingly soluble salt is defined as the product of the molar concentrations of the ions in a saturated solution of the sparingly s..

The order of reaction is determined with respect to each reactant in the reaction. The order of a reaction is the power to which the concentration of a reactant is raised. This is the order with respect to one reactant only. For the reaction where there are more than one reactants, the order of the..

The specific heat of a substance is the amount of heat required to increase the temperature of a unit mass of it through a unit temperature. Its units in cgs system are cal g -1 o C -1 . In mks system, it is measured in kilocal kg - 1 o C - 1 . The SI unit is J kg - 1 K - 1 . The above de..

If n N, then (1 + x) n is defined for all values of x and if n Q - N, then (1 + x) n is defined only when |x|<1. If n N, then (1 + x) n contains only n+1 terms and if n Q - N, then (1 + x) n contains infinitely many terms. In the expansion of (1 + x) n , the exponent of x goe..
