05.03 Gas Laws: Lab Report
Directions: Read/ Study all the lesson information in the 5.03 lesson then click the activity tab to perform two virtual labs. (There are recorded Teaching Videos for lesson 5.03. To view them click the “Help Sign” on the announcement page. Next scroll down to Lesson 5.03 stuff and you should see 5 part video links that will cover the lesson content.)
Virtual Lab 1- Part I: Boyle’s Law
A sample of gas is trapped in a sealed container, which has a movable lid. Moving the lid up or down will change the volume inside the container. You will use an attached manometer to measure the pressure inside the container.
1. Move the lid of the container up or down. Record the resulting volume and pressure…show more content…
Virtual Lab Part 2: Charles’s Law
1. Carefully measure the volume of the trapped gas using the graduations (markings) on the side of the container.
2. Read and record the temperature of the gas using the thermometer attached to the container.
3. Use the buttons on the heater to change the temperature of the gas. The volume of the gas will change in response to the temperature change. Notice that the container is sealed and the pressure is adjusted so that it remains constant. Measure and record the volume and temperature of the contained gas.
4. Continue this process until data is obtained for at least six different temperatures. Be sure that the temperatures represent a large range of values in order to help you answer questions about the relationship between temperature and volume.
Present all relevant data in a data table below. Include an observations section for any observations you made during the lab. Make sure you note the data needs to be converted before graphing.
