Introduction: Solubility is the “ability for a given substance, the solute, to dissolve in a solvent” . The effect of temperature on solubility is that when heat (energy) is added, it increases the speed on which molecules and particles move, therefore making it a quicker process. Where as with cooler temperatures there aren’t as many particles because the solvent doesn’t contain as much energy as warmer temperatures, therefore not dissolving as well as it could if it was warmer. To make jelly you first of all need to add boiling water to dissolve the sugar crystals and make sure they have completely dissolved before adding cold water to increase the amount, this is an example of the effect of temperature on solubility of sugar. The rate of solubility can depend on multiple factors such as the temperature of solvent, the size of the solute and how the solvent is stirred for example stirring time, big or small movements.

If the results were out of the range I would consider the experiment unreliable. It was an accurate experiment, as the method was performed the same for all 9 trials. The sugar was the same brand, the water was kept to the correct temperatures at 4 oC being the coldest, 20 oC and 100 oC being the warmest., as well as the amount of times stirring at 5 minutes and the amount of sugar added to the solvent was kept the same each time. The validity of this experiment was acceptable as the results presented were all accurate. Trends in the experiment were that in the first 2 experiments, 4 oC and 20 oC, 2 of the trials collected the same data. Also in Trial 2 of every temperature was lower or the same as the other data collected. To improve future experiments, finding a way to receive a cooler temperature with less energy and particle movement would be
