The quality of the water produced from the sewage treatment process matched the quality of the water in our current drinking water system. Whether the treated sewage water can be accepted as drinking water or not has to be found and commented on either way. Concept Introduction: Water pollution: It can be defined as alternation in physical, chemical and biological characteristics of water through natural or human activities and making it unsuitable for its designated use. Water treatment: when effluent discharged into a river body such as lake, river or sea a number of process occur like physical, chemical and biological characteristics of water change which causes loss of organism. The extent of damage depend upon type of pollutant present in effluent, non-bio degradable pollutant like mercury are most deadly as they accumulate in aquatic organism which lead to bio magnifications.

In the spectroscopic technique known as photoelectron spectroscopy (PES), ultraviolet radiation is directed at an atom or molecule. Electrons are ejected from the valence shell and their kinetic energies are measured. Since the energy of the incident ultraviolet photons is known and the kinetic energy of the ejected electron is measured, the ionization energy, I, can be deduced because total energy is conserved. (a) Show that the velocity, v, of the ejected electron and the frequency, n, of the incident radiation are related by hv = I + (1/2)mv^2? (b) Use this relation to calculate the ionization energy of a rubidium atom, knowing that light of wavelength 58.4 nm produces electrons with a velocity of 2,450 km/s Recall that 1 J = 1 kg.m^2/s^2

I) In Millikan's experiment, each droplet observed by the technicians contained an even number of electrons. If they had been unaware of this limitation, how would it have affected their report of an electron's charge?II) Millikan measured the charge of an electron in electrostatic units, esu. The data he collected included the following series of charges found on oil drops: 9.60 X 10^-10 esu, 1.92 X 10^-9 esu; 2.40 X 10^-9 esu; 2.88 X 10^-9 esu; and 4.80 X 10^-9 esu. (a) From this series, find the probable charge of the electron in electrostatic units. (b) Estimate the number of electrons in an oil drop with a charge of 6.72 X 10^-9 esu. The actual charge (in Coulombs) of an electron is 1.602 X 10^-19 C. What is the relationship between esu and Coulombs?
