Define newton's 1st and 2nd laws of motion and give an example of each law.

First Law: An object in motion will stay in motion unless acted on by an unbalanced force. An object at rest will stay at rest unless acted on by an unbalanced force.

Lets say a cup is sitting on a table, if you fall into that table and knock over the cup you are the unbalanced force acting upon the cup. The cup is at rest until you (the unbalanced force) acted upon it.

Second Law: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Say you are at the Supermarket. Its easier to push the empty shopping cart. Once the cart is filled you must exert more force to push it. This is because the empty cart has less mass than the full one.

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
