(1) Fig. 5.1 Which labelled feature reduces heat transferless by both conductor and convection? (ii) Explain why the named feature in () reduces heat transfer ty conduction and convection (c) Explain in terms of electron movement, what happens when a plastic becomes negatively charged by rubbing it with a piece of cloth pls help
ASAP ​

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

it would only be the stuff in module eight so you need to study all the lessons in that you also could check the flvs

hope this : )
