Relationship between pressure and volume Essay

Questions concord to the result of the experiment, the human birth surrounded by variables such as great deal and squash was inversely related. However, the represent that showed the relationship amid 1/ people and the pinch was at once related. Gas police force was defined by umpteen scientists. However, the relationship between volume and pressing was proven by Boyle who made Boyles laws which defined contract and volume are inversely proportional. If the twitch goes up, the volume depart go down and vice versa. However, if we identify the volume inversely, then the relationship between wedge and the inversed volume will be changed into directly proportional. KMT (Kinetic molecular(a) theory) helps to explain macroscopic properties of gases such as cart, temperature of volume, by considering their molecular composition and motion. It says that embrace is due to collisions between molecules moving at different velocities. If the gas is in a container, the collis ion with the wall is instantaneous and elastic. at that placefore, its baffle is changeable by pres certain or temperature. However, at some point, the volume does not change diminished when in that respect is no much(prenominal) space between molecules or the collision with wall is stronger than the pressure. As we tolerate see in the result of the experiment, at that place is large discrimination between weak pressures and smaller difference between strong pressures. At the end in that location is almost no difference between pressures. The separate graph that volume was inversely drawn shows unvaried increase which is directly proportion. We open fire also key out the shape of graph from the equation. The origin equation of Boyles law is P?1/V P=k(1/V) PV=k. shuttingFrom the experiment, I was able to determine the mathematical relationship between pressure and volume. According to the Boyles law, compress* book of account has exertion because pressure and volu me are inversely related to each other. To induce out the pressure, I had to fine out the mass and the area of collision because the pressure has a formula (Mass/Area). According to the formula, the pressure of a book had 251g/cm (1440/5.73 = 251g/cm). at that placefore, the pressure will be continuously changed by the flesh of books. It is not the end of the pressure. I had to add the substance pressure on the piston equals the pressure from the books add-on the atmospheric pressure. For the volume part, I just had to say the scale of spray that shown according to the number of books.The more books press the syringe, the less scale of volume was shown. From the Boyles law, P?1/V P=k(1/V), PV=k(constant) back tooth be deduced. Form the mathematical calculation based on the Boyles law, the volume was exactly decreased, when the pressure was increased. In addition, Pressure*Volume showed the constancy, even if it contained Brobdingnagian uncertainties. Therefore, the con clusion will be same as Boyles law that the pressure and the volume are inversely proportional. To select the graph which shows the relationship between pressure and volume more understandable, I supposed the small numbers (50-1000) of pressure that would give oft bigger volume by dividing constant from pressure. According to the graph, smaller number of pressure has bigger number of volume, and vice versa.LimitationThere 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 authority there was not any pressure between these. I think that was because of the supporting occasion 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 V olume, it had 8% of uncertainties so the biggest constancy was 1200 (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 cranky syringe, I had to make the balance point so my pressure by hands might work on the results.ImprovementFortunately, my experiment had a few mirthful points so it was rather successful. However, to improve my experiment, I read to figure it out the mass of the support 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 cut off the uncertainties, we use up 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 eq uipment that we do not need to find the balance point and put pressure by 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.
