Evaluating Boyle's Law
187 Words1 Pages
When dealing with ideal gases, we assume that the gas has no interaction with other gases. In this experiment, it was a safe to make such assumption since our gas was atmospheric gas and it was maintained at a constant temperature of 295.5 K. However, one aspect that was noticed that affected the accuracy of our results was keeping the

When you collect the gas through the eudiometer, the water inside the eudiometer gets displaced, evaporating until the pressure of the water outside is equal to the pressure inside. To correctly find the pressure of the gas, the pressure of the water vapor must be subtracted, as the two are mixed together. What is the limiting reactant for the reaction? What is the experimental evidence that you are basing it on?

Based on the obtained results from the experiment, the unknown liquid was determined to be methanol. The results were very close to the theoretical values, all within 15.92 % error. In this experiment it showed that the methanol have different intermolecular forces at work and at different vapor pressures implying that the amount of intermolecular forces they exhibit affects the vapor pressure. Possible source of error that occurred throughout the experiment was that the temperature was hard to control leading to the variances between the temperature of the reading in the water bath and the actual temperature causing slight changes in the vapor

Task 3 1. Why it important to work accurately and what is are the consequences of submitting inaccurate results? It is important to submit accurate results as the results that are submitted could potentially be used in a legal scrutiny case in court to help prosecute the offending company. The reason why the quality of the results must be so accurate is because if case goes to court the accused company will want to challenge the work you have carried out or your method or your results, they will employ a solicitor to help them win the case.

This lab contains two experiments that both test the knowledge of the gas law and how it applies to the state that is necessary to form a cloud and to calculate the rate of effusion of CO2 (carbon dioxide) leaving a balloon. If carbon dioxide is placed into a balloon for a period of time, then the carbon dioxide will effuse out of the balloon at a linear rate, because of the pressure that the gas is placing on the wall of the balloon that will allow it to escape from the balloon's microscopic pores. If a match is placed into a flask with room temperature water and heated water, then the resulting cloud that forms in the heated water will have a higher volume and a higher pressure than the cloud that forms in the room temperature water. The

It is imperative that observations are made in a deliberate manner that will aid in the acquisition of measurements. Our individual senses may be skewed, or ill prepared to capture the necessary data at the rate that it is presented. In order to supplement this ability, it may be advantageous to utilize available technology such as photographs or recordings (Babbie, 2017). In addition, errors could be the result of overgeneralization, assuming facts based on a limited sample of data. Selective observation (seeing only the desired results) and illogical reasoning (excepting something as fact that is not validated by known facts) (Babbie,

The law describes that when the pressure of a gas remains the same/constant, the volume of the gas is directly proportional to the temperature. This means that when the volume increases, the temperature increases, and oppositely the same would happen if the the volume had decreased. In the experiment, the law supports my results because when the volume increased, so did the temperature.

Also, the indicators that have been used in this are limited in number. By increasing the number of indicators the accuracy of the study can be increased dramatically. When the number of indicators used for analysis is lower not only will a lot of data not get considered but also the accuracy that one requires for the study will not be achieved.
