PPT-Lecture 7 Gases and Gas Exchange

Composition of the atmosphere Gas solubility Gas Exchange Fluxes Effect of wind Global CO 2 fluxes by gas exchange Emerson and Hedges Chpts 3 and 10 Sarmiento and Gruber 2002 Sinks for Anthropogenic Carbon. Chapter 5. E-mail: . benzene4president@gmail.com. Web-site: http://clas.sa.ucsb.edu/staff/terri/. Gases – Ch. 5. 1. Draw the following:. a. A closed monometer attached to a flask filled with CO at 250 . Tim . Styranec. Chemical Storekeeper. Why Here.  . Why . Here - Had training last three years. Have retraining once a year.. Thank . you - for working for the dept. each year. Excellent . job, great having experienced people.. 13.2 Gas exchange in single-celled organisms and insects. Learning outcomes. Students should be able to understand the following:. How single-celled organisms exchange gases. How terrestrial insects balance the need to exchange gases with the need to conserve water. Mr. Nelson. Chemistry. Properties of Gases. Gases are . fluids. Fluids are . any substance that flows. Gases are highly compressible. Example: . Tire pressure. Gases completely fill containers. Gases have . Chemistry—2. nd. semester. Properties. All gases share some physical properties:. Pressure (P). Volume (V). Temperature (T). Number of moles (n). These properties combine to describe the behavior of gases using the “gas laws”. 13.4 Gas exchange in the leaf of a plant. Learning outcomes. Students should be able to understand the following:. How plants exchange gases?. How the leaf of a dicotyledonous plant is adapted for efficient gas exchange. The solubility and saturation value for gases in seawater increase as temperature and salinity decrease and as pressure increases.. 1. . Solubility. is the ability of something to be dissolved and go into solution.. 2. Gas Laws. We will examine the quantitative relationships, or . empirical laws. , governing gases. . Basically, we will learn about equations that are available to calculate P, V, T, & n for gases. . Gases Kinetic Molecular Theory and Gas Laws Learning Objectives Be able to explain behavior of Gases using Kinetic Molecular Theory Explain relationship of volume, temperature, and pressure Use absolute temperature scale Gas Laws The atmosphere is made up of gases so we need to know the basic laws of how gases behave Gas laws describe the relationships between the 4 key parameters describing the behavior of gases Temperature (T) Gas Laws The atmosphere is made up of gases so we need to know the basic laws of how gases behave Gas laws describe the relationships between the key parameters describing the behavior of gases Temperature (T) Kinetic Molecular Theory of Gases. This is the six point model that is used to explain the behavior of gases. Points of the Kinetic Molecular Theory. 1. Gases are composed of atoms or molecules that have mass. In groups. discuss what is meant by the word “exchange”. Apply the word exchange to a biological concept. Exchange takes place over surfaces. Write down features of a good exchange surface. Which processes are used in the exchange of substances. A strong attraction to each other and a large volume . A strong attraction to each other and no volume . A weak attraction to each other and a large volume . A weak attraction to each other and no volume .
