A student drops three blocks from the same height and measures the time it takes for the blocks to hit the ground. Each block has a different mass. What is the dependent variable in the experiment?

the drop height

the volume of the blocks

the mass of the blocks

the time for the blocks to hit the ground

b) nuclear ive learned that in a pedtrodic table

listen, you cant how young you were.

"you didn't chose the stud life. the stud life chose you."

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
