PLS HELPThe picture below shows the setup for an experiment involving a 1000 ml beaker, sitting on a bumer, filled with 500 ml of water, where the bumer represents the Sun's energy, and the beaker of water represents Earth's oceans.

1000 L

500 m

Bumer

During the experiment, black pepper was added to the water as it boiled strongly, and the pepper moved in a circular pattern from the top

of the water to the bottom and back again. What does the circular pattern of the pepper represent?

it means there are 3 atoms of oxygen

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
