The percent errors for the first and second gas samples are approximately 6.44% and 1.70%, respectively.
To calculate the percent error for both gas samples, the formula ∣experimental value−actual value/ actual value∣×100 is applied, where the actual value for absolute zero in degrees Celsius is -273.15. For the first gas sample with an experimental value of -253.8°C, the percent error is calculated as ∣−253.8−(−273.15) /−273.15∣×100, resulting in an approximate percent error of 6.44%.
Similarly, for the second gas sample with an experimental value of -269.5°C, the percent error is calculated as ∣−269.5−(−273.15)/−273.15∣ ×100, yielding an approximate percent error of 1.70%. These values represent the relative deviations of the experimental temperatures from the actual value for absolute zero, indicating the accuracy of the measurements.
