Question
### Chemical Reaction Pressure Measurements During a chemical reaction conducted inside a sealed gas cylinder, a gaseous product is formed. The pressure \( P \) exerted by the gas has been recorded five times using a gauge calibrated in psig (pounds per square inch gauge). Below are the data from these measurements: #### Table 1. Pressure measurements of the oxygen generated by the chemical reaction inside a gas cylinder. | Run # | \( P \) (psig) | |-------|----------------| | 1 | 21.0 | | 2 | 20.2 | | 3 | 20.7 | | 4 | 21.3 | | 5 | 20.5 | ### Questions a. **Estimate the Type A uncertainty in these measurements. Be sure to include the units.** b. **Estimate the Type B uncertainty associated with these measurements. Be sure to include units.** c. **Determine the uncertainty in the measurement of pressure in the cylinder. Be sure to include units. State your answer as average +/- uncertainty.** --- **Type A Uncertainty** refers to the statistical variation from repeated measurements (i.e., precision) and can be estimated using standard deviation or standard error of the mean. **Type B Uncertainty** includes uncertainties from all known sources other than Type A, such as measurement device calibration, environmental factors, etc. These concepts help in understanding and quantifying the reliability and accuracy of experimental results in scientific research.
