PPT-Atmospheric Layers and gases

SUQ Why is the atmosphere important for humans Which gas is the most abundant What is the other 1 Why is each significant Co2 Water vapor Argon Ozone What happens to air pressure and temperature as one goes higher in the atmosphere. 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.. Diffusion plus Convection. ).  . Molecular Diffusion in Gases. Equimolar. . Counterdiffusion. A. B. B. A.  .  . In terms of mole fraction, . Molecular Diffusion in Gases. Uni. -component Diffusion. 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”. (work funded through the Great Lakes Restoration Initiative). Dr. Mark Cohen.

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 , Chloe . Kotzer. , Jared Llewellyn, & Kelsey Zola. Group 18- The Noble Gases. Noble gases make up a group of chemical elements with similar properties. The properties include . being odorless, colorless, low chemical reactivity, and are monatomic gases. Transport Solutions for Gases Non-flammablecryogenic gasesFlammable Proportions of gases in the atmosphere. Composition and evolution of the atmosphere. Combustion of fuels. Source of atmospheric pollutants.. Most fuels may also contain some . sulfur. .. Gases from burning fuels. 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.. 3.
