PPT-Kinetic Molecular Theory of Gases and the Gas Laws

Mr Nelson Chemistry 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 . and . Exothermic/Endothermic Reactions. Kinetic Theory. Kinetic Theory . - . A theory concerning the thermodynamic behavior of matter, especially the relationships among pressure, volume, and temperature in gases. . Kinetic Molecular Theory. Kinetic Molecular Theory . –. is the idea that matter is . ma. de from moving invisible particles. . The following are the principals of Kinetic Molecular Theory:. All matter is made up of tiny particles. Root Mean Squared, Effusion, Real Gases. Kinetic Molecular Theory of Gas. What is Kinetic energy?. Energy of motion. Kinetic theory of gases. Assume molecules are point masses (possess mass but no volume). Dr. N. K. Shukla. Associate Professor. Department of Chemistry. Mahatma Gandhi P.G. College. Gorakhpur-273001. Part I. Connecting the microscopic with macroscopic. Macroscopic properties. Gas is made of atoms or molecules that occupy a much larger space than the size of the constituent particles.. 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. Types of States of Matter. Solid. Liquid. Gas. Plasma. Beam. BEC, or Bose-Einstein Condensate. Zero State of Matter. Most Dense. Changes of State. Kinetic Energy (. kelvins. & . paschals. ). chemwiki.ucdavis.edu/. 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 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 ( 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 key parameters describing the behavior of gases Temperature (T) 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. Review . of the Properties of Solids, Liquids, and Gases. Kinetic Molecular Theory of Gases. Boyle’s Law, Charles’s Law, Gay-Lussac’s Law and the Combined Gas Law. . Dalton’s Law of Partial Pressure, Avogadro’s Law and the Ideal Gas Law. ; relation to internal energy density. Spherical velocity-space coordinates and the distribution of particle speeds. The equilibrium pdf for a homogeneous, isotropic (ideal) gas is . Maxwell’s distribution.
