From molecular view point, discuss the temperature dependence of susceptibility for diamagnetism, paramagnetism and ferromagnetism.

Give four differences between ferromagnetic, paramagnetic and diamagnetic substances ?

The value of intensity of magnetisation is small positive for a specimen. Is it diamagnetic or paramagnetic or ferromagnetic?

Fill ups At ……………………..temperature a ferromagnetic material passes over to paramagnetics.

In which type of material the magnetic susceptibility does not depend on temperature?

NiCl_2[P(C_2H_5)_2 (C_6H_5)]_2 exhibits temperature dependent magnetic behaviour (paramagnetic/diamagnetic). The coordination geometries of Ni^(2+) in the paramagnetic and diamagnetic states are respectively

What is recombination? Discuss the applications of recombination from the point of view of genetic engineering.

Vapour pessure of a liquid or a solution is the pressure exerted by the vapour in equilibrium with the liquid or solution at a particular temperature. It depends upon the nature of the liquid and temperature. It depends upon the nature of the liquid and temperature. According to Raoult's law in a solution, the vapour pressure of a component at a given temperature is equal to the mole fraction of that component in solution multiplied by the vapour pressure of that component in hte pue state. this solution in which each component obeys Raoult's law are called ideal solutions. there are two types of non ideal solutions, showing positive deviations and negative deviations from ideal behaviour. If liquid A and B form ideal solution, then

The following data was obtained for the dependence of the magnitude of electric field with distance from a reference point O, within the charge distribution in the shaded region show in the fig. Identify the charge distribution and justify your answer.

Surface tension is exhibited by liquids due to force of attraction between molecules of the liquid. The surface tension decreases with increase in temperature and vanishes at boiling point. Given that the latent heat of vaporation for water rho_(w) = 540kcal/kg ,mechanical equivalent heat =4.2j/cal Avogadro's No. N_A = 6.0 xx 10^26 , and the molecular weight of water M_A = 18 kg for 1 k mole. Estimate the energy required for oe molecule of water to evaporate.
