How does the polar property of water relate to cohesion? How does the polar property of water relate to adhesion? What is the reason why hydrocarbons are not soluble in water? List at least five important properties of water and discuss why these properties of water are important to organisms...
The image below shows a glass pipe with water flowing inside it. Suppose that you change the material of the pipe from glass to one that has relative roughness of 0.002. What would the effect of the change of rou...
the oxygen atom of one molecule faces the hydrogen atom of another molecule and it accounts for the greater viscosity of water compared to like molecules. It also accounts for the water's unique solvent capabilities. Hydrogen bond strength varies from 4 Kj to 50 Kj per mole of hydrog...
Explain the differences between cohesion and adhesion in water. Why is the scientific method important? Using the six steps of the scientific method, explain why each step is important when performing an experiment. Why is density dependence important in multicellular organisms? Why is it important ...
(even if it's just air). The apparent discrepency that's been discussed above is rooted in the fact that two very different processes are under consideration: cohesion vs. adhesion. Because of tight packging, as we've seen, PTFE has a high energy of cohesion. But, this still doesn't...
water. A strong base is the one that gives away the hydroxyl ion readily while the weak base loses the ion slowly. But, Ammonia does not behave as either acid or base according to the Bronsted-Lowry theory. As ammonia does not have extra hydroxyl ion to donate, it cannot be classified ...
several fresh wateranimalssurvive below the ice inside waters, as ice on the top floats. It prevents the water underneath not to freeze and create an environment for the life, to survive. Otherwise, at cold temperatures rivers and lakes would have been filled with ice killing the creatures ...
