Learning task 2:answer the problems below A 0.30kg carts move on the air track of 1.2m/s. It collides with and sticks to another cart of mass 500g, which was stationary before collision. What is the velocity of the combined carts after collision?

answer: you could do some invislibe ink.

explanation: i will tell you how to if u answer my question.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

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
