Evaluating Boyle's Law

However, since there was the 2 percent of uncertainty, that would be enough to cause

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.

The authors attempt to determine the cause for this discrepancy

A Multidisciplinary defense of the Gaseous

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

However, the experimental values were different due to human error. Error Analysis Discuss the

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

Interestingly enough, Boyle's gas law, Gay-Lussac's gas law, and Avogadro's gas law are connected in a way similar to how branches are connected to a tree. If the Ideal gas law can be considered the 'trunk' of the tree, then Boyle's, Gay- Lussac's , and Avogadro's gas laws are the 'branches'. To better understand this analogy, it is important to understand how each of the laws can be derived from the Ideal Gas Law. Gay-Lussac's law states that the pressure of an ideal gas is directly proportional to its temperature in kelvin, assuming that the amount of gas and the volume of the gas remain constant. The equation for Gay-Lassac's law would look something like: V = T k, where V is volume, T is temperature, and k is a constant.

And also not all variables were controlled. Finally the information is provided by the observer which could be biased o

Bottom Chamber liquid: Ethanol has a very low boiling point. When you heat the bottom chamber with your hand, the liquid molecules in the hand boiler increase in kinetic energy (increased temperature); the liquid expands. This rise in temperature causes the liquid to start to evaporate. Because there is some evaporation, but no condensation, the equilibrium is ruined in the hand boiler until the evaporated molecules lose kinetic energy and become liquid again (cool off). Bottom Chamber gas: When you apply heat to the bottom chamber, the gas increases in pressure because of the evaporated molecules.

For Part C, 1.0atm of N2 gas was added to the vessel, bringing the total pressure to

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.

P=KC Graham’s Law states that the rate of diffusion of a gas is inversely proportional to the square root of its density under given conditions of temperature and pressure. (Rate Gas A)/(Rate Gas B)=√(MMGasB/MMGasA) Dalton’s Law states that the total pressure of a gas in a container is the sum of the partial pressures of the individual gases in the container (Helmenstine, 2013). P_T= P_1+P_2+P_3+⋯ Combined Gas

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.

Although it is a fairly simple method, errors and biases are easily introduced and care must be taken to ensure sources of errors are
