Some people believe that singing joyful, soothing songs to plants helps the plants grow faster. Without sufficient scientific evidence to support this idea, we cannot call it
. Currently, the idea is considered a myth or, at best, an interesting
that needs to be tested seriously in controlled conditions. If sufficient scientific evidence is gathered to prove the accuracy of the claim, it will help support the broader
that living beings respond to human emotions.

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
