Molecular Motion and the Transfer of Matter,red from one geographical location to another, particular questions frequently occur: What amount of material will be moved? In what direction will it be moved? How far will the material be moved? How long will it take to move the material? What are the driving forces which cause the movement?

North America and the Caribbean,ons have been obtained in the form of infinite series of terms. In practice, solutions are usually required in the form of tabulated numerical values or graphs — for example, values of concentration in different parts of a medium at successive times. Such values can be obtained by evaluating a suffi

Richard Jenkins,Matthew MendelsohnIt has already been demonstrated that concentration . depends upon space co-ordinates and upon time. An example of such a relationship is given on page 21, equation (2.1). If . and . are both taken to be unity, the relationship becomes
