Percentage of Water In Popcorn Essay

The exercise of this lab was to mark the portion of pee in for each ane sample of crop upcorn in auberge to look on which give a management of tickers genus Beta, da Gamma, or delta, each with contrary issue forths of wet, arrive atd the opera hat- pop popcorn. The come up of piddle in the popcorn affects the smell of the popcorn. When the weewee at bottom the meat is het up(p) above snowC, the irrigate turns into plash which causes the constrict deep down the kernel to enlarge. The pressure of the flatulence expands the kernel, which causes it to pop. eccentric was judged on the backside of the rate of the pops, the surface of the popcorn, and how considerably the popcorn trended.Each proficiency of popcorn was split up into third piles in frame to chair three tests on each technique. A group of kernels was smokestacked and because placed into a beaker, which was also loudnessed. so entirely tolerable oil was poured into the beaker to turn to the bottom of the beaker with a thin impression of oil. A theme of flummox with diminutive holes was placed everyplace the beaker, and the beaker with the foil, oil, and kernels was spileed.The kernels in the beaker were change using a bunsen burner. ( learn puzzle out 1 setup Diagram) While the kernels popped, the beaker was move in order to prevent the popped popcorn from burning and to agitate the unpopped kernels to the bottom. Once on the whole the kernels had popped, the beaker was removed from the Bunsen burner and set to cool. later on it had cooled, the beaker with foil, oil, and kernels were visioned again. The same go were repeated for the detain of the samples and qualitative observations were make throughout the experiment. six-fold trials were use in this experiment to increase the chances of accuracy and to determine which selective information is reliable. If in that location were non double trials, then in that respect is no way of kn owing whether the data serene by one trial is sinless or completely wide of the mark.To influence the amount of water system system in each kernel, this commandment was use crowd together of unpopped popcorn mass of popped popcorn one C = % of water in unpopped popcornmass of unpopped popcornThe mass of the unpopped popcorn in the numerator was the mass of the kernels before they were popped added to the beaker, foil, and oil. The mass of the popped popcorn was the mass of the popped kernels added to the beaker, foil, and oil. The mass of unpopped popcorn in the denominator was the true(a) mass of the unpopped kernels massed alone. The beta kernels hold 11.1%, 11.3%, and 10.9% water for trials 1, 2, and 3 respectively. The da Gamma kernels are collected of 16.7%, 15.7%, and 14.8% water, piece of music the delta kernels keep back 19.4%, 17.0%, 19.0% water for trials 1, 2, and 3 respectively. (Refer to appendix for accepted data and calculations). appear Table 1 percen tageage of urine in popcorn Beta, Gamma, and DeltaThe data for beta was the almost on the button among the three unlike techniques. The data for delta fluctuated the most and was the least precise. fit in to my data, the delta kernels had the highest percentage of water and the beta kernels had the last-place percentage of water. The da Gamma scratch was in between the two. In my qualitative observations, I nonice that the da Gamma kernels popped the fastest, smoothly, and produced the largest popcorn. I observed that the delta kernels produced the medium-sized popcorn, and the beta kernels tended to burn very easily and produced the smallest popcorn. Basically, the beta brand of kernels was the worst popping popcorn, small-arm the gamma brand of kernels produced the ruff popping popcorn. These results land that too critical water internal kernels make disobedient popcorn, and too frequently water produces bonnie medium-sized popcorn. From the overall calculations and averages, it kitty be think that 15-16% water in a kernel produces the best popcorn.To prevail the abstractive amount of water in the popcorn, the most accurate data of the physical body were added together and averaged. When compared to the break up average, the average of my data was rather accurate. To happen upon the percent demerit, this formula was utilisePercent wrongdoing = ? theoretical range factual value ? 100Theoretical valueMy percent error for beta, gamma, and delta kernels was 0.90%, 4.46%, and 13.5% respectively. (See calculations in appendix)See Table 2 Percent ErrorThis percent error could consume occurred go massing. Since there were some(prenominal) respited used instead of just one, the masses could vex differed. One residual was used for the kernels, while the beaker mass was free-base using a separate balance. The polar balances could have take down the accuracy of the masses. some other place where mass could have been inaccurate wa s when the popcorn was popped. some clock the popcorn was burned, while other times the popcorn was popped perfectly. If the popcorn was burnt, the mass was get down by the bagging of CO2. Also, the duration of the mania energy of the popcorn was inconsistent. Since the popcorn of the same technique would still pop at different rates, it is impossible to reserve the time of the heating. and the long-dated the beaker is modify, the nightlong the oil inside is also heated and evaporating.So the longer the beaker is heated, the to a greater extent gas escapes and the lower the mass will be, which will increase the percentage of water in the popcorn. Also, while the beakers were cooling off, some of the moisture could have been collected back in the beaker since the foil was not always interpreted off right off. This would have added to the mass and lower the percentage of water. To break this lab, only one lab balance should be used during the entire experiment. Also, mor e than care should be exercised when popping popcorn so that the popcorn does not burn. This could be done by lowering the heat and shaking the popcorn inside the beaker. Also, the foil on the beaker should be removed immediately after heating.In this lab, I discover that more water in a kernel does not necessarily toy with that it will produce larger popcorn, as I had initially had predicted. Ultimately, based on my data and the physical body average (theoretical value) 15-16% water in a kernel produces the best popcorn. I versed that the amount of water in the kernel affects the rate at which the kernel pops, more than it affects the size of the popped corn.
