Exp. 22 – Ideal Gas Law and Absolute Temperature
Dear Students,
Please carefully read the instructions given in your lab manual (pages 241-245) about this experiment and follow the outlined procedure (pages 245-250) while watching the lab video from the link given below. This experiment requires computer data acquisition, so you won’t be able to collect data by just watching the video. The video only demonstrates how the experiment works. But, we recorded plenty of data for you to use, which are given in a zip file below. Please watch the video in full screen and in full HD (1080p) resolution. Some of the details might be difficult to see on a smaller window and lower resolution. To make it easier to follow the procedure, you will see labels on the video showing which part of the procedure is being performed.
