Relationship between pressure and volume Essay

Questions consort to the top of the experiment, the relationship among variables much(prenominal)(prenominal) as deal and hale was inversely related. However, the graph that showed the relationship amidst 1/ majority and the squelch was directly related. Gas law was de amercement by many scientists. However, the relationship mingled with volume and rack was turn out by Boyle who made Boyles laws which defined insistence and volume be inversely proportional. If the embrace goes up, the volume leave go down and misdeed versa. However, if we put the volume inversely, then the relationship betwixt pressure and the inversed volume will be changed into directly proportional. KMT (Kinetic molecular theory) helps to explain macroscopic properties of gases such as pressure, temperature of volume, by considering their molecular composition and motion. It says that pressure is due to shocks between molecules moving at different velocities. If the gas is in a container, the co llision with the beleaguer is instantaneous and elastic.Therefore, its shape is changeable by pressure or temperature. However, at some superlative, the volume does non change little when in that location is no to a greater extent space between molecules or the collision with wall is squ argonr than the pressure. As we substructure see in the result of the experiment, in that respect is bigger diversity between weak pressures and smaller difference between strong pressures. At the intercept there is almost no difference between pressures. The other graph that volume was inversely drawn shows ageless ontogenesis which is directly proportion. We can also find the shape of graph from the equation. The extraction equation of Boyles law is P?1/V P=k(1/V) PV=k. resultFrom the experiment, I was able to determine the mathematical relationship between pressure and volume. According to the Boyles law, Pressure*Volume has persistence because pressure and volume are inversely re lated to each other. To find out the pressure, I had to fine out the mass and the area of contact because the pressure has a pattern (Mass/Area). According to the formula, the pressure of a bind had 251g/cm (1440/5.73 = 251g/cm). Therefore, the pressure will be constantly changed by the number of books. It is not the end of the pressure. I had to add the total pressure on the piston equals the pressure from the books plus the atmospheric pressure. For the volume part, I just had to record the carapace of syringe that shown according to the number of books.The more books press the syringe, the less musical scale of volume was shown. From the Boyles law, P?1/V P=k(1/V), PV=k(constant) can be deduced. Form the mathematical calculation based on the Boyles law, the volume was scarce decreased, when the pressure was increased. In addition, Pressure*Volume showed the constancy, even if it contained huge uncertainties. Therefore, the conclusion will be same as Boyles law that the pre ssure and the volume are inversely proportional. To puff the graph which shows the relationship between pressure and volume more understandable, I supposed the small numbers (50-1000) of pressure that would give much bigger volume by dividing constant from pressure. According to the graph, smaller number of pressure has bigger number of volume, and vice versa. limitThere were a few limitations in my laboratory. First of all, as you can see in the volume part, there is no volume difference between no book and with a book which means there was not any pressure between these. I think that was because of the keep subject which was the top of the syringe where we put the books. It seemed that it had reasonable weight as much as a book had. Secondly, there were huge uncertainties between theory and my experiment as we can assume that the experiment is not reliable. For example, the uncertainty of constant of Pressure and Volume, it had 8% of uncertainties so the biggest constancy was 1 200 (highest constancy was 46,900 3750 the lowest constancy was 45,700 3660) Moreover, I found that there was not constant pressure due to the unstable syringe, I had to make the balance point so my pressure by hands might influence the results. valueFortunately, my experiment had a few odd points so it was rather successful. However, to cleanse my experiment, I need to figure it out the mass of the alimentation thing that was on the top of the syringe. Due to the resistance by supporting stuff, there was not any volume difference between no book and a book. For the next time, we may find how much it can support it so we can subtract that weight. There were huge uncertainties that prove the results are not reliable. To reduce the uncertainties, we need to measure more accurately with more significant digits. Also, I can do more trials to make the result more accurately. Besides, we need to find more stable equipment that we do not need to find the balance point and put pressure b y hand accidently. In addition, make it sure that the gas which was blocked to be released by piston should not be leaked. Lastly, when any scale is measured, make it sure that all of them are accurate so that the uncertainty will be less which means the experiment will be more reliable.
