By: Sean Larson ID# 21792768 Partner: Evan Kellogg Abstract: This lab was performed to experimentally determine the temperature at absolute zero, T ABS is normally equal to -273.15°C when there are perfect conditions, and to try and prove the idea of an “ideal” gas. There are many different types of error that can take place in the experiment to cause a different T ABS .
