The effect of salt on the boiling temperature of water research paper Essay

Project formulate PlanEveryone knows that pissing grinds at 212F, but does hang oning flavour to a cumulus of body of body of weewee supply make it churn at a higher temperature? Being a person that cooks much at home, I wanted to test the debated supposition that make uping sodium chloride to my piddle pass on make it boil prompter. One of my partners says it does raise the temperature and therefore cooks it red-hot. My other friend says it solely helps it taste better.Literature Review delay flavour is often added to weewee before the turn process in hopes that the body of water will boil faster. It has been argued that the simmering temperature residual is insignificant with a petty(a) green goddess of water. However, when adding salt to larger amounts of water, the change is much noticeable.Southwest query Institute states that the heat message of salt water is less than that of utter(a) water, which direction that it takes less energy to raise th e temperature of the salt water 1 C. than pure water. The time it takes a pot of water to boil is controlled by three things, prime(prenominal) is how much heat you put into the pot, second is how fast the temperature rises and third is the boiling pass of the liquid (Southwest Research Institute, 2014).Salt elevates the boiling temperature of water using a process known as boiling point elevation. With water being a known response and salt a non-volatile solute, when you add salt to the water, it makes the water an impure solvent, and raises its boiling point above that of pure solvents (Effect of Salt on the boiling Temperature of wet). Experimental Design StepsWater will be boil four different times as follows1.2 cups of distilled water are added to a 2 quart homework pota. First run add NO salt this is the controlb. Second run add 1 Tablespoon of dodge salt ladder 1c. Third run add 1 Tablespoon of hedge salt Trial 2d.Fourth run add 1 Tablespoon of table salt Trial 3 2. For severally run, add together water to boil3. For separately run, record the highest temperature training of the boiling water4. After first with third runs, allow pot and burner to cool5. dust pot after to each one run to loose salt residueReasoningA regular(prenominal) recipe will call for a germinate of salt in the water. The articles I read do me believe that adding more salt would make the temperature contrast more noticeable, I upped the salt to 1 tablespoon of salt to each pot of water per run, instead of a dash. Adding a dash of salt could reorient the results, because when adding a dash, you will not have the homogeneous measurement of salt to each pot of water as you would when step the salt with a tablespoon. In order to reduce error, so I employ three trials.Sequence of EventsDuring each trial I will be measuring the temperature of the water with a thermometer. at a time it reaches its highest temperature, I will record it in my data table. This wi ll be the process for each trial.Tools, Technologies, and Measurement UnitsTable SaltDistilled Water2 Quart Cooking PotPint measuring cupTeaspoon and tablespoon measuring spoonsThermometer (Degrees Fahrenheit) breathing in spoonStove top burner (electric) shiftingsIndependent uncertain Amount of salt added to the waterDependent Variable Temperature at which the water boilsControlled Variables Temperature of kitchen stove setting, pot, type of water, stigma of salt, amount of water, thermometerThreat Reduction to Internal grimnessBy washing the pot and thermometer between each trial, I will reduce the amount of salt residue that is on the pot that could alter my results. I will use the same heating unit, pot, and thermometer each time to get more valid results.theoryThe hypothesis of this sample is that adding table salt to water will raise the boiling temperature of the water.

Variations in the boiling temperature may be contributed to slight variations in the measurements of the salt added to the water. It is important to measure both the water and salt exactly to ensure accurate results. enamour MethodsFor each run, 2 cups of water were added to a 2 quart saucepan 1 tablespoon of salt was hence added to the water and stirred to mix the two ingredients together. The saucepan was accordingly put on the stove and brought to a boil. Once the water reached a full boil the final temperature was recorded using a Go-Temp thermometer. The tools and methods used in this are appropriate to the experiment.ResultsThe results were larger than anticipated. The average temperature of the water with the salt was 21 5.1 degrees Fahrenheit, while the temperature of the control was 212.7 degrees Fahrenheit. This was a difference of 2.4 degrees. ConclusionConfirmation of HypothesisMy hypothesis was confirmed. Adding table salt to water causes the water to boil at a higher temperature. The temperature readings were hard to make. Oven mitts had to be irresolute to keep my hands from getting burned. I had to be sure that the thermometer wasnt too close to the stove or the temperature would be skewed.Experimental Design as a Key FactorHow you design your experiment is key to helping you keep your results reliable and valid. You only need one independent variable. If you have more than one, you wont know which one is rattling affecting your results, it will also be harder to measure. reservation as many variables as possible changeless will help increase the reliability of the experiment. retortBy following this plan and report, you can bend this experiment. One might try adding different amounts of salt to see if there is a point at which the amount of salt added stops increasing the boiling point. Evaluation of ValidityReplicating this experiment will add to the validity of my results and others results. If the experiment is replicated numerous times this will add to thevalidity, resulting in a more accurate conclusion. It is important to measure both the water and salt accurately to ensure that the results collected are as accurate as possible.ReferencesDoes water boil faster if you put salt in the water? (n.d.).
