Comparing Popcorn And Soread

The aim of the experiment was to find out how changing the mass effects the rise of the temperature of water.

Have you ever wondered how popcorn kernels get left behind? Research by food scientist Bruce Hamaker from Perdue University suggests that it is lack of moisture. Moisture helps the corn kernel pop. You should store your popcorn in a cupboard where it is dry, never put your un-popped popcorn in the refrigerator because that will cause it to lose moisture. I am figuring out which brand of popcorn leaves least amount of kernels.

The purpose of this experiment was to test multiple brands of popcorn under the same setting in order to conclude which one statistically popped the most kernels. I tested the butter flavor of Orville Redenbacher, Wal-mart’s Great Value brand, and Pop Weavers. The different bags of popcorn were popped in the same microwave for the same amount of time, 3 minutes and 15 seconds. Then, the popped corn was counted, as well as the un-popped kernels, in order to determine a ratio, and then I recorded the results in the data table. I repeated these steps two more times for a total of 3 trails for each brand. Then I compared the ratios of all the bags to determine which brand yielded the most popped corn. The statistical technique used to evaluate the data was to find a ratio between the number of kernels in the bottom of the bowl and the number of popped kernels. To find this, I divided the number of the actual popped corns by the total number of kernels left in the bottom of the bowl. The ratios and percent were then compared. Once all my results were in the data table, I averaged the 3 trials for each brand of popcorn.

The percentage error for both trials came to 79.6% and 85% so if only 20% of the energy was released onto the can the rest of it was released into the atmosphere and its surrounding areas. As a result, the amount of energy being released onto the can was short but the rest of energy eventually released at a high percentage because the energy does not disappear, but the energy goes out to surrounding and the air. Significantly, every calculation was taken accurately but the error percentage somehow proved inaccurate because we used the equation Q=m*Cp*T to calculate how much energy was being released by the sample and then we also used it calculate the Calories per gram which there we figured out the changes within the experiment then when we subtracted the result and divided it by 6.4 then times it by 100 it gives the amount of the percentage error to determine how much energy was released and find out where it ended all up to be. In conclusion, the energy released during combustion reaction goes to the air and everything else around the energy because due to the amount energy being released it can tell us how much energy went missing and find out where it all went to determine the error that went on during the

In order to measure the heats of reactions, add the reactants into the calorimeter and measure the difference between the initial and final temperature. The temperature difference helps us calculate the heat released or absorbed by the reaction. The equation for calorimetry is q=mc(ΔT). ΔT is the temperature change, m is the mass, c is the specific heat capacity of the solution, and q is the heat transfer. Given that the experiment is operated under constant pressure in the lab, the temperature change is due to the enthalpy of the reaction, therefore the heat of the reaction can be calculated.

This scientific experiment is to gauge the amount of kernels popped when the storage temperatures of the kernels are changed. Does freezing popcorn kernels for 24 hours yield more or less popped kernels than popcorn kernels stored at room temperature? By performing this experiment we can decide how to maximize our food potential. We will purchase six identical brands of popcorn from the local food store that have the same ingredients, weight and brand name. We will take three of the bags of popcorn kernels and store it in a standard household freezer for twenty four hours. The temperature

5.Once test kernel has popped, pour in the popcorn kernels into the pot, put the pot top on, and immediately start timer for seconds.

Paragraph 1 - How the Law of Conservation of Matter is supported by the experimental demonstrations: In the law of conservation particles and materials are neither created nor destroyed . It was similar towards the experimental demonstrations because nothing changed or destroyed in the processes .Kinetic and potential energy was used in the experiments.

When the final mass was measured the excess water in the potato cube might have not been completely removed, thus it adds to the final mass of the potato cubes. This acts as a major error because it gives an inaccurate representation of the actual percentage change in mass of the potato cubes, also while measuring the mass of each cube of potato; the value fluctuated and was not consistent.

Temperature is very important in this experiment (Energy & Heat). Temperature affects the amount of steam, and steam makes the popcorn pop. So if the temperature is low, it will take more time to pop. If the temperature is high it will take less time to pop. In conclusion, the lower the temperature, the less steam created, and the higher temperature, the more steam created. Resulting in the popping time needed. The temperature is very important, because the temperature determines when the popcorn will pop. So if the temperature is low or way high, the popcorn will either burn or not pop (Walker).

In this unit we have conducted research and experiments on our chosen reactions to create the highest exothermic reaction for the The Heat-and-Eat meal pack will use a chemical reaction that involves two reactants. Reactant 1 is a solid and Reactant 2 is a liquid.

There were three reasons why we chose to do this experiment with boiling fizzy drinks. We chose this experiment because we were wondering how much sugar is actually in a fizzy drink. We also wanted to find how much energy is in an energy drink. Another reason why we chose to do this experiment, is we also wanted to find out how much energy sugar produces when lit on fire. So we joined both of these ideas together and said what happens if we boil fizzy drinks until they are caramelized and then light them of fire to see how much energy is produced by heating up 50 ml of water in a

The purpose of the container is not only to keep the combustion reaction contained, but also to keep the volume of the set-up constant. This container is filled with pure oxygen in order to facilitate the combustion reaction before being submerged in a liquid (usually distilled water) which will absorb the heat of the reaction, evidenced by the change in temperature read in the thermometer. Normally used in the food industry to determine the amount of calories certain food items have, the bomb calorimeter is used to determine the enthalpy of combustion of substances. The apparatus is used in particular for determining that specific quantity since the “bomb” is built to withstand the particularly high pressures which come from combustion of the sample 2. Before the naphthalene sample was analyzed, the bomb calorimeter was calibrated through the use of a benzoic acid standard.

We will be using 6 different fuels to heat up 100ml of water, and find out the changes of the temperature. We will measure the temperatures of the water before and after the experiment. We will burn heat the water for exactly 2 minutes, and check the changes in temperature. The change in temperature will allow us to work out the energy given off the fuel by using this formula:

The independent variable of this experiment were the different types of the solutions used, while the dependent variable was the mass of the cucumber slices. The constants were, the amount of liquid used and the time the cucumbers were left in the solution. While the control was the cucumber left in the cup with no solution. The students made a hypothesis saying that they believe that the cucumber slices put into the salt solution would decrease in mass while the cucumber put in the distilled water would increase in mass. In the end, the results of the experiment supported the students
