Diffusion is one of several transport phenomena that occur in nature. A distinguishing feature of diffusion is that it results in mixing or mass transport‚ without requiring bulk motion. Thus‚ diffusion should not be confused with convection‚ or advections‚ which are other transport mechanisms that utilize bulk motion to move particles from one place to another. In Latin‚ "diffundere" means "to spread out". There are two ways to introduce the notion of diffusion: either a phenomenological approach

In this poem‚ Kinnell demonstrates a profound metaphoric relationship between the tangible objects of blackberries‚ and the intangible objects of words. He feels an attraction to blackberries such as with taste‚ touch‚ and appearance. That notion is supported throughout the poem. For example‚ line 7 states the following: "Lifting the stalks to my mouth‚ the ripest berries‚" illustrating his love for the taste of delectable fruits. Furthermore‚ it demonstrates the sensory characteristics of touch

that centre on memories of his childhood‚ growing up on a farm in the Irish countryside. Here he recalls the annual experience of picking wild fruit in late summer. Heaney uses assonance in his phrase ’glossy purple clot’ to describe the first blackberry that ripened and stood out from others pictured with the simile as being still ’hard as a knot’. Heaney compares the taste of the first ripe berry to the sweetness of ’thickened wine’. He uses the metaphor ’summer’s blood’ to express the redness

The Correlation between the Diffusion Rate of a Substance and its Molecular Weight ABSTRACT To test the effect of molecular weight on the rate of diffusion‚ various experiments were performed. One of which is the glass tube test wherein cotton balls of the same size were moistened in two different substances (NH4OH and HCl). These cotton balls were plugged at each side of a glass tube. After some time‚ formation of a white ring occurred. The white ring‚ in fact‚ is a product of the reaction between

Introduction: Diffusion is vital to many life functions of a cell‚ it allow the transportation of vitally important nutrients and compounds without the expenditure of excess metabolic energy. To explain diffusion‚ it is as if a bottle of perfume is opened at one end of the room‚ then in a short amount of time a person at the other end of the room can detect the scent of the perfume; this is the process of diffusion. Diffusion is a movement from a higher
