Name_______________ Date ___________ Period _______ AICE Marine - Understanding Solubility If you can successfully answer these questions then you will be able to pass the quiz on Monday. Understanding the Basics How does kinetic energy from solutes move in…. - High temperatures - Low temperatures What does solubility mean? How does temperature affect solubility? Understanding Salinity What occurs to solutes such as NaCl once it is stirred in water? - Explain the chemistry What occurs to those solutes once temperature is involved? How does temperature affect salinity levels? How do you know? How does precipitation, runoff, and evaporation affect salinity levels? Factors Affecting Solubility Why are gases in the atmosphere in equilibrium with gases in the seawater? What determines gas solubility when speaking about the gas itself? How does temperature affect solubility of gases? Describe atmospheric pressure and describe how it affects solubility. Why do you find more gases in cold water than you do in warmer waters? Explain what happens to kinetic energy and how that plays a role in solubility. How does depthness levels affect solubility of gases. How does salinity affect gas levels? There are less gases present in higher temperatures, then what explains the high levels of DO in the surface layer. What occurs to DO at the oxygen minimum layer? Why does this occur? After the oxygen minimum layer DO increases. What are the factors that cause DO to rise? Explain what happens to the kinetic energy in gas molecules in the surface layer as opposed to kinetic energy deeper in the ocean. Thinking about kinetic energy and about ion movements now explain why the gases are increasing with deepness levels.
