The Effect of Salt on Boiling Temperature of Water

EXPERIMENTAL SCIENCE PROJECTSThe impression of Salt on the simmering Temperature of Water(Initially prepared by a quaternary Grade student)To quickly jump to a section below filter onINITIAL OBSERVATIONCooking instructions tell you to add salinity to piddle system before boil it. PROJECT TITLEThe Effect of Salt on the Boiling Temperature of WaterPURPOSE OF THE PROJECTTo find out how table table saltiness affects the turn temperature of body of irrigate. HYPOTHESISAdding table salt to boiling water will cause the water to boil at a higher(prenominal) temperature.MATERIALS AND EQUIPMENTTable Salt Distilled Water 2 dry quart Cooking Pot Pint sum up cup Teaspoon and tablespoonful measuring spoons Thermometer Stirring spoon EXPERIMENTAL PROCEDUREBoil one quart of distilled water on a stove. Measure the temperature of the boiling water. Record the highest temperature reading. This is the control to oppose with. Measure out table salt using a kitchen measuring spoon. Level the spoonful. Add the measured salt to the boiling water and stir.Measure the temperature of the boiling water with the salt in it. Record the highest temperature reading. Repeat for other amounts of salt. DATAData Obtained 2/25/95, Mankato, MN gist of boiling water2 Cups Temperature of boiling water (Control)212. 9F Amount of table salt added to boiling water solve 11 Tbl. Temperature of boiling water afterwards adding salt maneuver 1215. 6F Additional amount of table salt added to boiling water discharge 21 Tbl. Temperature of boiling water after adding salt Run 2218. F EXPERIMENTAL OBSERVATIONSWhen the salt was added to boiling water it bubbled up more, and then stop boiling. Shortly afterwards, it boiled again. If the thermometer extends beyond the outside of the pot it reads a higher temperature. Heat from the stove burner makes the thermometer read higher. Keep the thermometer over the pot when devising temperature measurements. CALCULATIONSTotal amount of table salt add ed for Run 1 0 + 1 = 1 Tbl. Total amount of table salt added for Run 2 1 + 1 = 2 Tbl.RESULTS Temperature of boiling water (Control)212. 9F Amount of table salt added to boiling water Run 11 Tbl. Temperature of boiling water after adding salt Run 1215. 6F Total amount of table salt added to boiling water Run 22 Tbl. Temperature of boiling water after adding salt Run 2218. 3F Amount of Table Salt Added VersusWater Boiling TemperatureCONCLUSIONSIs the hypothesis correct? Yes. Adding table salt to water causes the water to boil at a higher temperature. Problems with doing the experiments.The temperature readings were effortful to make. Gloves had to be worn to keep my hands from getting too hot. Had to be careful that the stove heat was not hitting the thermometer. Other things learned. Be careful when adding salt to boiling water. It makes the water boil vigorously for a second or two. RELATED QUESTIONSWhy do you think readying instructions tell you to add salt when boiling water? When the water is hotter, you can cook food faster. Salt also makes the food sample better. HOME-0 -0 .. /index. html
