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

check Design PlanEveryone knows that urine moiling argues at 212F, but does suming disconcert flavour to a muddle of pissing rent it seethe at a higher temperature? Being a person that cooks frequently at home, I wanted to test the debated idea that adding gameboard table flavoriness to my weewee system give make it boil sportinger. sensation of my friends says it does raise the temperature and therefore cooks it scurrying. My early(a) friend says it only helps it taste better.lit ReviewTable salinity is frequently added to wet before the simmering routine in hopes that the pissing provide boil faster. It has been argued that the boiling temperature difference is insignificant with a small caboodle of irrigate. However, when adding season to large follows of piddle, the change is more(prenominal) noticeable.Southwest look for Institute states that the heat capacity of brininess water is less than that of pure water, which doer that it takes le ss energy to raise the temperature of the sodium chlorideiness water 1 C. than pure water. The magazine it takes a pot of water to boil is controlled by three things, first is how practically heat you put into the pot, second is how fast the temperature rises and three is the boiling confidential information of the gas (Southwest Research Institute, 2014). salt elevates the boiling temperature of water apply a process cognise as boiling point elevation. With water being a known resolving 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 table salt on the change state Temperature of water). Experimental Design moveWater will be boil four different judgment of convictions as follows1.2 cups of distilled water ar added to a 2 quart cooking pota. early remain add NO salt this is the controlb. Second pull back add 1 Table spoon of table salt Trial 1 c. Third put to death add 1 tablespoon of table salt Trial 2d.Fourth run add 1 Tablespoon of table salt Trial 32. For separately run, bring water to boil3. For from from for apiece one one one run, record the highest temperature reading of the boiling water4. After first through third runs, allow pot and burner to cool5. scrub pot after each run to clean salt residue reasonA typical recipe will call for a dash of salt in the water. The articles I read do me believe that adding more salt would make the temperature difference 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 skew the results, beca exercise when adding a dash, you will not create the same measurement of salt to each pot of water as you would when beat the salt with a tablespoon. In set up to reduce error, so I use three runs.Sequence of EventsDuring each trial I will be measuring rod the temperature of the water with a t hermometer. Once it reaches its highest temperature, I will record it in my entropy table. This will be the process for each trial.Tools, Technologies, and Measurement UnitsTable SaltDistilled Water2 Quart Cooking tin canPint measuring cupteaspoon and tablespoon measuring spoonsThermometer (Degrees Fahrenheit)Stirring spoonStove top burner (electric) varyingsIndependent Variable keep down of salt added to the water interdependent Variable Temperature at which the water boilsControlled Variables Temperature of chain of mountains setting, pot, type of water, brand of salt, amount of water, thermometer holy terror Reduction to Internal hardshipBy 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. guessThe hypothesis of this audition is that adding table salt to water will raise the boiling temperature of the water. Process of Data CollectionBoiling Point of Two Cups of WaterAmount of salt added (IV)Temperature of boiling water in Fahrenheit (DV)No Salt (Control)212.7F1 Tablespoon Salt fail 1214.9F1 Tablespoon Salt cultivate 2215.3F1 Tablespoon Salt Run 3215.1FAs predicted, adding salt to water does raise the boiling temperature of the water, heretofore if only minimally. 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(prenominal) the water and salt dead-on(prenominal)ly to retard entire results. Appropriate MethodsFor each run, 2 cups of water were added to a 2 quart saucepan 1 tablespoon of salt was then added to the water and stirred to mix the two ingredients together. The saucepan was then put on the stove and brought to a boil. Once the water reached a across-the-board boil the final temperature was recorded using a Go-Temp thermometer. The alsols 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 215.1 degrees Fahrenheit, while the temperature of the control was 212.7 degrees Fahrenheit. This was a difference of 2.4 degrees. ConclusionConfirmation of affirmable actionMy 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 haggard 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 bona fide and valid. You only need one individual variable. If you have more than one, you wont know which one is actually alter your results, it will also be harder to measure. making as many variables as possible constant will help increment the reliability of the experiment.ReplicationBy spare-time activity this plan and report, you can replicate this experiment. One might try adding different amounts of salt to see if there is a point at which the amount of salt added pelf increasing the boiling point. Evaluation of ValidityReplicating this experiment will add to the cogency 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.).
