A student places a 12-gram cube of ice inside a container. After six hours, the student returns to observe the contents of the container. Which sentence suggests that the container is an open system? O A. The container contains 12 grams of liquid water and no ice. . O B. The container contains 12 grams of ice and no liquid water. OC. The container contains 8 grams of liquid water and no ice. OD The container contains 8 grams of ice and 4 grams of liquid water. OE The container contains 8 grams of liquid water and 4 grams of water

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
