Our solar system is thought to have started with the birth of our sun, which formed from a cloud of interstellar dust and gas. this cloud condensed and eventually collapsed from its own gravitational pull. the heat and pressure built up, forming a protostar. eventually nuclear fusion began. planets formed from remaining dust and gas orbiting the protostar.
this explanation best describes
the nebular theory
the big bang theory
the inflation theory
the condensation theory

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
