Maxwell's Distribution of Molecular Speeds - On plotting a fraction of molecules having different speeds against the speeds of the molecules (along x-axis) a curve known as Maxwell's distribution curve is obtained. The important features of which are: The fra..

Maxwell's Speed Distribution Law - The rms speed of an oxygen molecule in a sample at 300 K is about 480m/s. This does not mean that the speed of each molecule is 480 m/s. Many of the molecules have speed less than 480m/s and many have speed more than 480m/s. Maxwell d..

The energy of thermal radiation emitted per unit time by a black body of surface ..

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/m 2 - K 4..

. f = e - E a / R T (22) The effect of this factor on k can be best explained with an example. Examples 13: The reaction of nitric oxide (NO) with chlorine (Cl 2 ) is believed to occur in a single step. The activation energy for the reaction is 8.5 x 10 4 J / mol. At 298 K the fraction of..

Due to resonance, the p -electron charge in benzene gets distributed over greater area, i.e., gets delocalized. Delocalization results in the energy of the resonance hybrid decreasing relative to the contributing structures, by about 150 kJ mol - 1 . This decrease in ene..

In an intrinsic semiconductor, the energy gap E g is 1 eV. Its hole mobility is very much smaller than electron mobility and is independent of temperature. What is the ratio between conductivity at 600 K and that at 300 K? Assume that the temperature dependence of intrinsic carrier concen..

Numerical 01 - In an intrinsic semiconductor, the energy gap E g is 1 eV. Its hole mobility is very much smaller than electron mobility and is independent of temperature. What is the ratio between conductivity at 600 K and that at 300 K? Assume that the temperature dependence of intrinsic..

It is material in which the laser action is made to take place. It may be solid, liquid or gas. Many lasers are named after the material used e.g. ruby laser, He-Ne laser, CO 2 laser, Nd: YAG laser etc. The most important characteristic requirement for the laser medium is that we should be able t..
