Evelyn Torres Chervenak wk3 Kinetic Theory Objectives • Describe how the kinetic-molecular theory is used to explain how gases behave at different temperatures. (Exploration 1) • Analyze data that shows how gas particle mass affects that gas’s behavior. (Exploration 2) Based on the mass of the object, the gas particle can move quickly in higher temperature or slower depending on the mass components. • Describe the Maxwell-Boltzmann Distribution. (Explorations 1 and 2) With increasing energy some of the particles will be found to be slower Description of Activity The kinetic-molecular theory states that a collection of gas molecules’ average kinetic energy has a specific value at any given temperature. In this activity, you will study how temperature and gas particle mass affect the frequency distribution of gas particle speeds. You will examine and analyze speed frequency distribution graphs. This distribution is called the Maxwell-Boltzmann Distribution. Jump Start 1. What is kinetic energy? It is energy in motion 2. What is thermal energy? Movement of atoms and molecules 3. What happens to a gas’s thermal energy as that gas’s temperature increases? The particles decreases in speed 4. What happens to the average speeds of the particles in a gas when that gas’s temperature
