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”. Chemistry. Ms. . Piela. 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 . 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.. By the end of the lesson you should know. The names of the states of matter. That matter is made of particles. How the particles are arranged in solids liquids . and gases. The names of the changes of state. 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) 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..
