BEHAVIOR OF GASES Beta Science
Overview In this PowerPoint, you will learn how gases behave when subjected to changes in temperature and pressure. You will also learn about two important gas laws.
Effects of Temperature on Gas Particles Temperature: a measure of how hot or cold something is. Specifically, temperature is a measure of the movement of particles. The hotter a substance is, the faster the particles in the substance will move. The colder a substance is, the slower the particles in the substance will move.
Volume The volume of a gas depends on the container that the gas is in. Particles of gasses are easily compressible compared to those of liquids and solids.
Pressure Pressure: The amount of force exerted on a given area of surface. Think of pressure as the amount of of times the particles of a gas hit the inside of their container. Ex. there are more particles of air in a basketball than in a beach ball, therefore, a basketball feels harder than a beach ball.
Boyles Law Boyles Law: states that the volume of a gas is inversely proportional to the pressure of a gas when temperature is constant. As the pressure of a gas increases, the volume decreases by the same amount. (Show Boyles Law Video)
Charless Law Charless Law: the volume of a gas is directly proportional to the temperature of a gas when pressure is constant. While Boyles Law deals with volume and pressure, Charless Law deals with volume of a gas while considering temperature. In Charless Law, pressure is constant which means it stays the same all of the time. (Ping-Pong Ball Demonstration)
