13 Students modeled the formation and weathering of a volcano in the ocean. The students drew a line around an
aquarium to represent sea level. Clay was pushed through a hole in the bottom of the aquarium to represent the
formation of the volcano. Students then cut sections of the clay, using a small wire, to represent weathering of
the volcanic formation. Throughout the investigation, students took a series of pictures of their model.

What order of topographic maps best matches the order of the model pictures?

your answer would be “dry”

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
