Now you shine light with a continuous energy distribution and you observe absorption lines at the following photon energies: 1eV, 3eV, 4eV, and 7eV. Using the information from the two experiments described, select the energies that correspond to all the energy levels of this atom. Hint: Similar to potential energy, the absolute values of the energy levels are arbitrary to a constant, but the difference in energies between levels is not. Follow the convention that the ground state energy (the lowest energy state) is the negative of the ionization energy and base your other answers around this. O eV

Now you turn off the light and run a beam of electrons through the gas. The kinetic energy of the electrons is 3.5 eV. Collisions of the electrons in the beam with the atoms in the gas exite the atoms to states above the ground state. Select all the possible energies of the emitted photons from this gas.

state the principle of separating two immiscible liquids by separating funnel. describe an activity with diagram to separate a mixture of water and kerosene oil. answer: immiscible layers separate out in layers depending on their densities in separating funne

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
