Absolute Zero is defined as the temperature where all molecular motion stops. In order to experimentally determine this value, a student placed sealed Erlenmeyer flask with a sample of gas, a temperature probe and a pressure probe on a heating element. Data was collected over a period of 25 minutes. The graph below displays the results. What is the experimentally determined temperature for Absolute Zero? Evaluate the reliability of the data and suggest any factors that may affect the results of the experiment. Note that the equation of the line is y = 3.29x - 300. *

Transcribed Image Text:Absolute Zero is defined as the temperature where all molecular motion stops. In
order to experimentally determine this value, a student placed sealed Erlenmeyer
flask with a sample of gas, a temperature probe and a pressure probe on a
heating element. Data was collected over a period of 25 minutes. The graph
below displays the results. What is the experimentally determined temperature
for Absolute Zero? Evaluate the reliability of the data and suggest any factors
that may affect the results of the experiment. Note that the equation of the line
is y = 3.29x - 300. *
