Effect of Sugar on the Melting Rate of (Coke) Ice Cubes

Effect of Sugar on the Melting send of (blow) Ice CubesIntroductionThere was constant information coming up about lollipop ponderous the freezing halt of field glass therefore shortening the run clip of the fruitcake. This try out will be conducted as hope to solidify research, atomic number 6 crackpot cubes will be used in the test sea captain puff ice cubs which contain carbohyd compute, and Coke zero ice cubes which contain no added lollipop. This experiment will provide more veritable information for scientists for real life applications such as combine ice off roads as high-velocity and easier way, clearing snow off roads or to clear ice for room for infrastructure and construction.AimTo see the effect of sugar on the melting rate of ice cubes ( pilot light coke sugar, and Coke Zero no sugar).HypothesisThe sugar in the lord Coke ice cubes will cause the ice cubes to melt faster than the Coke Zero ice cubes. This is because sugar lowers the freezing point o f water/most liquids.Material listMethodPour 10mL of Original Coke into a separated/slotted ice cube tray using a pipet and measuring cylinder to make legitimate that all the ice cubes are the same size (leave the ice trays in the deep-freeze overnight).Pour 10mL Coke Zero into a separated/slotted ice cube tray using a pipette and measuring cylinder to make sure that all the ice cubes are the same size (leave the ice trays in the freezer overnight).Place heat source in front or on summit of bench and switch it on.Record room temperature and air temperature before removing ice cubes form the freezer.Place superstar of each ice cube on a separate plate and start the timer.Time how presbyopic it takes for the ice cubes to melt.Take photos of the melting of the ice cubes.Write down results of the experiment including temperatures and times.Clean out plates and allow them dry before repeating the experiment around 8 times or until your results are consistent, reliable and close.Va riablesResultsImagesDiscussionI stated in my hypothesis that the Original Coke would melt faster because of its confine containing sugar whereas, Coke Zero does not. This is experiment was conducted on the basis of the research on what makes ice melts fastest. Substances that fragmentise in water lower the freezing point of the solution. This is an example of a colligative property.In this experiment, I investigated whether sugar affected the rate at which ice (cubes) melted. The reason I thought that the Original Coke would melt faster is because it contained lots of sugar and the reason I thought the Coke Zero would melt sluggish (than Original Coke) is because it has no natural sugar in it but instead it contains artificial sweeteners.On TV or in other countries (because we dont have ice/snow on the streets in Australia unless youre in the mountains), trucks are usually seen driving through streets covered with snow or ice, scatter a mixture of sand, gravel and salt on the ic e/snow to de-ice the roads (melt the degree of ice/snow on the road). The lowered freezing point because of the poured mixture means that snow and ice can melt even if the weather is supposed to be freezing water. This is an example of freezing point depression (the decreasing of melting point of a substance/molecule). I decided to see if sugar would have the same effect as salt as they are not so disparate when it comes to their molecular properties.My results supported that my hypothesis and made my research reliable, The Original Coke melted significantly faster than the Coke Zero (as shown in images 4 and 6) . My results were repeated seven* times in order to pick up reliable data. The graph created from the table of results show the average melting times for each persona of coke ice cube, it shows that Original Coke melted significantly (almost 300+ seconds in various instances) faster than the Coke Zero.The biggest difficulty I encountered was controlling the temperature of the air, plates and the temperature of the room. I set my experiment up in front of a gas heater in the living room where there were little things which would interfere with my experiment, making sure that each type of ice cube was the 30 centimetres away from the heat source, I began the experiment. Each type of ice cube was placed on the same type of plate at the same time for each repeat of the experiment. The temperatures were measured with 2 types of thermometers (an ordinary scientific grade thermometer and an IR thermometer1) during the experiment and the temperatures fluctuated from among 42oC and 50oC.. However, both types of ice cubes were exposed to the same increase during the experiment so the average melting rate results should not have been affected.The amount by which the freezing point is lowered depends only on the numerate of molecules dissolved, not on their chemical nature of the substance used because of this, my thoughts changed. Although my prediction2 w as correct, I still do not completely know what it was that changed the melting rate of the ice because I do not have scientific grade equipment or a laboratory to conduct a full scale experiment, but I suspect that it may have to do with Original coke having more soluble substances/material than Coke Zero. I could also conduct an experiment to discover the truth behind that theory by test the evaporation times of each type of Cola. (But thats for another time)ConclusionMy results show that the Original Coke ice cubes melt faster than Coke Zero ice cubes. I suspect that the sugar in Original Coke caused the ice cube to melt faster. However, freezing point depression depends on the amount of molecules dissolved, and not on the chemical nature or make up of the molecules. Therefore, the presence or absence of sugar in the Coke ice cubes may not have been the reason for my different melting rates.BibliographyNaveC.R. (n.d.).
