Document Content and Description Below

Introduction: In this simulation, you will explore the relationship of volume, temperature, and pressure in a gas. You will also discover how concentration and temperature affect the rate of diffusi... on of gases. 1. Follow the link to open the “Gas Properties” Simulation. 2. Click the “Ideal” tab. Part 1: Gas Properties – Temperature, Pressure and Volume 3. In this part of the lab, you will explore how gases behave when you change the temperature and volume of a system. 4. Look at the different parts of the simulation. Notice the Pressure Gauge, the “Heat/Cool” Bucket, the thermometer and the pump. 5. Click on the drop-down box above the thermometer and change the temperature units from °K to °C. 7. Click and drag the handle on the tire pump one time. What happened in the simulation when you did this? 8. Now that there is matter in the box, there will also be a temperature and a pressure. Look at the pressure gauge and the thermometer. Record the temperature and pressure below. Temperature 27 degrees celsius Pressure Around 5 or 6 atm 9. Use the “Heat/Cold” bucket to raise the temperature in the box. Click and hold the slider over the “Heat”. What happened to the pressure in the box when you raised the temperature? Record the pressure once it stabilizes. Thr pressure also increased until the lid came off Pressure The pressure never stabilized 10. Look the box that contains the gas particles. Use the handle to make the box about half as big. What happened to the pressure of the gas when you decreased the volume of the box? Record the pressure once it stabilizes. The pressure increased [Show More]
