PPT-Breathing & exchange of gases

BreathingExternal respiration The process of exchange of O2 from the atmosphere with CO2 produced by the cells Respiratory Organs Direct respiration by diffusion from the environment sponges coelenterates flat worms etc. 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. 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.. Function of Respiration. SBI 3U1. What is the function of the . Respiratory System?. To that ensure that . oxygen. is brought in and . carbon dioxide. is removed from each cell in the body…. . The 4 stages of Respiration:. Aziz AlSa’ad-Nasser Alabduljaleel-Abdulkareem AbuTaleb-Aziz AlOthman . 1.3 Vocabulary . Ultraviolet radiation:. rays of light that cannot be seen and that are a little bit shorter than the rays of violet light. Partial Pressure, . Gases in Chemical . Reactions . & KMT. Partial Pressures of Gases in Mixtures. Each gas, in a mixture of gases. , exerts . a specific amount of pressure. This pressure can be calculated using the ideal gas law:. 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. . The SI unit of pressure is the . pascal. (Pa).. . One . standard atmosphere (. atm. ). is the pressure required to support 760 mm of mercury in a mercury barometer at 25°C. . 13.1. 13.1. 13.1. 13.1. Behavior of Gases Chapter 3.2 Behavior of Gases What behaviors do gases display? Do they behave the same all the time? What variables are involved with gas behavior? Variables Pressure – the amount of collisions between gas particles and walls of the container (balloon). Measured in kilopascals ( 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. Breathing(External respiration) . The . process of exchange of O2 from the atmosphere with CO2 produced by the cells.. Respiratory Organs . • Direct respiration by diffusion from the environment – sponges, coelenterates, flat worms etc.. Which gases will leaves be exchanging?. Gas Exchange in Leaves. What features will gas exchange organs have to maximise the rate of exchange?. Large surface area, short diffusion pathway, concentration gradient. As per BS 6164 in 15.6 section. The hazardous nature of gaseous contaminants in the tunnel atmosphere should be taken into account, as some are toxic, flammable/potentially explosive, radioactive or asphyxiant. It should be recognized that some contaminants display a combination of toxic and potentially explosive properties. It should also be recognized that the monitoring and control of such gases in a tunnel atmosphere can be difficult because the concentrations rarely remain constant throughout a working day..
