Topic 10 section 1 Assessment Statements Statement Number Assessment Statement 1011 State the equation of state for an ideal gas 1012 Describe the difference between an ideal gas and a real gas. And Mixtures and Movements. Ideal Gas Law. To calculate the number of moles of gas. PV = . nRT. R : ideal gas constant. R = 8.31 (. L·kPa. )/ (. mol·K. ). Varriables. Example Problem. A deep underground cavern contains 2.24 x 10. Chapter 16.3. 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 (. Under what types of pressure do gases behave ideally?. Under what type of temperatures do gases behave ideally?. We originally defined ideal gases with as series of requirements. These included, no volume, elastic collisions, and they do not interact. Match these requirements with the conditions above. . P. V. . =. . n. R. T. P. . = pressure in . atm. V. = volume in liters. n. = moles. R. = proportionality constant. . = 0.08206 L . atm. / . mol. ·. K. T. = temperature in . Kelvins. . Holds closely at . An Ideal Gas. All gas laws are based on the assumption that gasses behave “ideally”. An . i. deal gas:. Moves in all directions and in straight lines. There is no loss in kinetic energy in collisions. Gases. August 6, 2011 Robert Iafe. Chemistry in the News. 2. Polymer nicotine trap is composed of a . porphyrin. derivative (black), in which amide pincers (green) are attached to the zinc (violet) containing macrocycle (blue). The nicotine molecule is shown in red.. 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 (. 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 ( 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. 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 .
