PPT-Chapter 14 Gases Gas Pressure

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 25C 131 131 131 131. Chapter 5.

Variables Pressure – the amount of collisions between gas particles and walls of the container (balloon). Measured in kilopascals ( 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 4 key parameters describing the behavior of gases Temperature (T) Solids, Liquids, & Gases Chapter 7 The Nature of Gases Indefinite shape and indefinite volume expand to fill their containers compressible Fluid – they flow Low density 1/1000 the density of the equivalent liquid or solid Gas Pressure.

Particle Theory. All . matter consists of many, very small particles . The particles . are constantly moving or in a continual state of motion. . The . degree to which the particles move is determined by the amount of energy they have and their relationship to other particles. . 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. 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..
