conclusion for coke and mentos experiment

Conclusion: The conclusion is a brief summary of the main findings of the study and their implications. The Wint-o-Green Lifesavers are rougher than the Mentos by a factor of 5, but the mass lost during these reactions is comparable. Thank you so much. Mentos Lab Report - Google Docs The work required to form a bubble in sugar water and aspartame is 74% and 67%, respectively, of the work required to form a bubble in pure water. [18], The eruption is caused by a physical reaction, rather than any chemical reaction. Mentos Geyser Experiment - Mentos & Coke Experiment - The Lab Carbon dioxide creates the bubbles in soda. But it has nothing to do with the mint Mentos actual flavor. Given the ingredients listed on Diet Coke, there is more aspartame than potassium benzoate in Diet Coke per unit volume. Note that the contact angle for the aspartame and potassium benzoate solutions is less than the contact angle for pure water, indicating a decrease in the surface tension. For each of the samples a (10m)2 image was acquired, and the root-mean-square (rms) roughness in the image was reported. ", "MythBusters: Diet Coke and Mentos MiniMyth", "Toying with the Diet Coke and Mentos experiment", "How Many Bubbles Are in the Foam Produced during the Candy-Cola Soda Geyser? students used this simple device to monitor the kinetics of foam production in the Diet Coke and Mentos experiment and to draw conclusions about the system. The scale bar for (a) is 100m and for (b) is 20m. From after-school activities and science classroom activities to STEM club experiments, our website is one of the most trusted resources for fun, age-appropriate experiments for kids of all ages. Did what you hypothesize happen? It comes with six fun experiments, a test tube rack, fizzing tablet and vegetable oil chemicals to play around with. The seltzer water and tonic water trials were 1l bottles with 16g of Mint Mentos added; all other trials were 30g of solid material added to a 2l bottle of liquid. [20][12][14][17] It has been claimed that gelatin and gum arabic in the Mentos candy enhance the fountain,[12][14][26] but experiments have shown that these candy additives do not affect the fountain. In this case, were changing the number of Mentos dropped into each bottle, so everything else has to stay the same. We use cookies to ensure that we give you the best experience on our website. Figure 1(a) qualitatively demonstrates that the small cubic table salt grains have a high surface area to volume ratio, thus providing many growth sites for the carbon dioxide in the Diet Coke. This hypothesis was also proven false as students used this simple device to monitor the kinetics of foam production in the Diet Coke and Mentos experiment and to draw conclusions about the system. So, if you want some quick and easy fun, get some paper towels becausewere about to make a sweet mess. Place the index card and candies over the mouth of the bottle. Because the level of carbonation in these products might be different from the Coke products, the seltzer and tonic water results should be considered independently from the Coca-Cola product trials. They also hypothesized that the rough surface of the Mentos can help break the strong polar attraction that water molecules have for each other by providing growth sites for the carbon dioxide, agreeing with scientists such as Lee Marek and Steve Spangler.2 Although they identified the prime ingredients, they did not sufficiently explain why those ingredients affect the explosion, nor did they provide direct proof of the roughness of the Mentosa tall order for an hour-long television program. This experiment investigates if small changes in your diet can alter your basal body temperature. Grobe, F., & Voltz, S. The Science of Coke and Mentos.
