	The in-person version of this lab has ~ 10 demo stations for which each group of student will rotate through. At each station are instructions. For this online version, in a best case scenario, each demo should be documented in your lab notebook under the demo name heading. Some demos require additional calculations. Please see the "'''''In your notebook...'''''" heading below indicating the information that should be recorded in your notebook (or paper).

-:- You will notice that i showed the trendline equation for 1 data set --> y = 2.8052x +795.48. Since the y = volume and x = temperature, what value might you expect to get if we were able to cool the flask down so that there was zero volume? volume = 2.8052 * temperature +795.48, or at volume = 0; 0 = 2.8052 * temperature +795.48 --> solving for temperature = -284 <sup>o</sup>C ~ -273 <sup>o</sup>C = 0 K <-- "absolute zero".

 ''Take home: Temperature and volume are directly proportional. This experiment also confirmed/predicted the value for absolute zero, the theoretically lowest temperature that can be reached."
