taden has found a table of the atmospheric layers of the sun. however, he can’t make out the names of the layers in the chart.

a 4 column by 3 row table. column one is untitled with the following entries: position, thickness, temperature. column 2 is titled a with the following entries: lowest, 100 kilometers, 5,500. column 3 is titled b with the following entries: middle, 2000 kilometers, 6,000 to 20,000. column 4 is titled c with the following entries: outermost, millions of kilometers, 2,000,000.what are the names of the sun’s layers described in columns a, b, and c?

a. a: corona; b: photosphere; c: chromosphere
b. a: core; b: chromosphere; c: photosphere
c. a: chromosphere; b: corona; c: core
d. a: photosphere; b: chromosphere; c: corona

they are all solids.

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
