=Taro stated that when someone hits a golf ball with a club, the amount of energy the ball has changes, the amount of energy that the club has changes, and the total energy of the system that includes the ball and the club increases. Which best explains Taro’s error? The amount of energy that the ball has does not change.
The amount of energy that the club has does not change.
The total energy of the system remains the same.
The total energy of the system decreases.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

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
