Using the diagram below at what point is potential energy the highest on the roller coaster and at what point is kinetic energy highest on the roller coaster. Be sure to include definitions of the two types of energy in your response.

i just learnt this recently but i need to look through my notes again

the answer is 303.15 or 303

it is stable as it is in group 0 which have full outer shells of electrons

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
