Plan It! Plastic or Wood?
Two students in a science classroom are debating about whether the tables
are made of wood or plastic. As the teacher passes by, she suggests, "Use
cell theory to find the truth!"
SEP Plan Investigations Propose a scientific investigation to determine
whether the tables are wooden or plastic. Include your hypothesis, what
steps the students should take, and any materials they might need to carry
out the procedure.

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
