*WORTH 13 POINTS When bringing a positively charged rod near an object to charge it by induction.

a) the charge on the rod remains intact so it can be used again to charge several objectd by induction

b) the object gains a negative charge

c) contact is not mafr by the rod, but there is contact with the ground

d) all or the above are true

e) all of the above are false

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

the correct answer would be b) volume versus temperature, because they are also directly proportional.
