 * PURPOSE**
 * Determine how the surface area and the temperature affect the number of solutes into the solvent of water


 * HYPOTHESIS**
 * I believe that the loose sugar in 100C water will dissolve the fastest


 * MATERIALS**
 * hot plate
 * beaker
 * thermometer
 * sugar cubes
 * loose sugar
 * plastic spoon
 * oven mitts
 * stopwatch
 * water


 * PROCEDURE**
 * Put 100ml of water in 2 beakers each.
 * Place the beaker on a hot plate until it reaches (room temperature, 40, 60, 80, 100) degrees Celsius.
 * Once hot enough, use oven mitts to take off of the hot plate.
 * Place 2 sugar cubes in one beaker and place one teaspoon of loose sugar on the other.
 * When sugar is put inside the beaker, use the stopwatch to time how long it takes for the sugar to dissolve.
 * Once dissolved, stop the stopwatch timer and record observations


 * OBSERVATIONS AND GRAPHS**



This graph shows the first and second trial for the loose sugar. Most of these observations were evened out, but some like the room temperature bars and the 80C bars were drastically different from each other. Errors like these could have occurred because of several variables. One of those being because of mixing the beaker with a spoon. This is done to speed up the time to dissolve. Another common error could have happened because the temperature will drop when it has been taken off of the hot plate and when the beaker is surrounded by cooler air.

This bar chart shows that the cooler that the water gets, the faster a sugar cube will dissolve. This graph is more accurate than the sugar graph because the results from trial 1 is relatively close to the trial 2 tests. This happened because a variable that could cause errors was taken out. Since the sugar cubes are compact and are one big piece, it would be useless to mix it with a spoon unless the cube was broken up by the spoon, which would cause errors in the final results. This graph also shows that the sugar cubes are more likely to last in water than the loose sugar.

According to the sugar cube trend line, the sugar cubes will last longest in room temperature water but as the water gets hotter, the faster it will dissolve. The same applies for the loose sugar, according to the loose sugar trend line, except that the change is very minimal in average.


 * REFLECTION QUESTIONS**
 * Infer which would actually dissolve faster, a whole sugar cube or loose sugar in ice cold water?
 * In ice cold water, an ice cube will last longer than loose sugar. According to the averages graph, a sugar cube will last longer in room temperature water than loose sugar. So if the room temperature water was replace with ice cold water, the sugar cube will last longer a lot longer.
 * What factors can you infer speed up the dissolving rate of the solute?
 * Possible factors that could speed up the dissolving rate would include things like the rate that the hot water would cool down once it is taken off of the hot plate. The surroundings of the beaker (such as air) could slowly cool down the water. Another Variable could be how long a beaker was stirred with a spoon. this would have an impact on the sugar because the water is moving and pushing against the sugar. Also, the beakers were not clean. Anything that could have been remaining in the beaker could have had an impact on just about anything and everything in the experiment.


 * CONCLUSION**
 * In conclusion, the sugar cubes lost longest in colder water but as it increases in temperature, the faster it will dissolve. The loose sugar lasts the longest in colder water without dissolving, although it dissolving in hot water has no major difference from it dissolving in colder water. The hypothesis is correct and the graphs and charts prove it. If I were to change one thing about it, it would be adding more trials.
