Answer the questions below. When you have finished, submit this assignment to your teacher by the due date for full credit.
The x-intercept corresponds to where the volume would be zero and the temperature can be no lower, defined as absolute zero. Absolute zero is 0 K. Compare your results to those expected. How close to absolute zero was your intercept? Why might your value be different from absolute zero?From Part 2 of the lab activity, plot a graph of volume vs. temperature (in kelvins) with the two data points that resulted from your experiment. Draw a straight line connecting the two points, thus assuming a linear relationship between volume and temperature. Extend this line back to intercept the x-axis.
- Consider all parts of the experiments that you have just performed.
- What conclusions can you make about the relationship between the volume of a gas and its temperature?
- What conclusions can you make about the relationship between the volume of a gas and its pressure?
- What possible variables have you not accounted for? As you did the procedures, is it possible that the atmospheric pressure may have changed? If it did change over the course of your experiment, then how would your results have been affected?
