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.. 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”. The Kinetic-Molecular Theory of Matter. Gases. Behavior of Atoms. Kinetic-molecular theory. .  . based on the idea that particles of matter are always in motion. Can be used to explain the properties of solids, liquids, and gases in terms of the energy of the atoms and the forces that act between them. 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 ( 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. . The particles are far apart.. The particles move very fast.. The particles have no attraction nor repulsion for each other.. The fact that they have no definite shape or volume – they take the shape of the container.. 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.. 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 . Non-Renewable. Energy. From Fossil Fuels. How are they formed? . What are the different types? . Why do we need to stop using them? . https://www.bbc.co.uk/bitesize/topics/z6wwxnb/articles/ztxwqty. .
