Examples of increase in entropy of the system should be identified. Concept introduction: The increase in entropy of the system results from randomness of atoms, higher the randomness more positive will be the entropy. Even transformation of solid into liquid results in increase in entropy of the system by increasing the randomness. The randomness between the atoms increases from solid to liquid then to gas because in solids the atoms areclosely packed due to which the randomness in atoms is very low.

Question

Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).

Both columns are packed with the same stationary phase, spherical particles with 1-um diameter. A) When the columns were prepared, the figure shows that the column with the larger diameter has more packing irregularities. Explain this observation. B) Predict what affect this should have on band broadening and discuss your prediction using the van Deemter terms. C) Does this figure support your explanations in application question 33? Explain why or why not and make any changes in your answers in light of this figure. Figure 4 SEM images of sections of packed columns for a) 750 and b) 30-um-i.d. capillary columns.³
