Objectives: Students will be able to observe the relationship between the volume and pressure of a gas, while keeping the temperature constant, by manipulating the volume slider in the simulation and noting the corresponding change in pressure. Students will be able to explain the behavior of gas particles in terms of their speed and random motion by observing their movements in the simulation and describing how they collide with the container walls and with each other. Students will be able to predict the effect ofchanging the temperature on the behavior of gas particles by manipulating the temperature slider in the simulation and making observations about the speed and behavior of the gas particles. Mate rials: ' Pen, paper * Laptop or smart phone with internet connection ' SIMULATION: 6. What, is the effect of increasing the pressure on the behavior of gas particles, while keeping the temperature and volume constant? 7. How does changing the volume of a gas affect the number of gas particles that collide with the container walls? 8. How does the simulation demonstrate the random motion of gas particles in a container? 9. What is the effect of increasing the temperature of a gas on the number of gas particles that escape from the container? 10. How can the simulation be used to explore the relationship between gas properties, such as pressure, volume, and temperature, and the gas laws, such as Boyle's law and Charles's law
