The science fair topic at hand is whether or not chemical compounds affect water 's heat resistance/reception. In other words, how does the temperature of water (H2O) change when chemical compounds - such as sodium chloride and sucrose - are added? In this experiment, the independent variable is the chemical compound being tested while the dependent variable is the temperature of the water. The constants are the surface being tested on which is a stove, the amount of water being used, the amount of grams used for the sodium chloride and the sucrose, and the time that is set for the water to heat up. What is controlled in the experiment is the pot of water with no chemical compounds in it. The measurements are in "mg" and "mL" using a measuring cup and in Fahrenheit using a thermometer. The hypothesis is that the pot filled with the mixture of salt and water will have the lowest temperature because salt is known for its ability to preserve food so maybe it will somehow be able to preserve the water from the heat. This hypothesis will be tested with an experiment. The materials included in this experiment are three pots, 25g of salt and sugar each, a measuring cup, three thermometers, 70 mL of water per pot, a stove, and a timer. In the procedure, three pots will be filled with 70 mL of water. One pot will contain 25 g of salt and another will contain 25g of…
