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

cast purport PlanEveryone knows that piddle travails at 212F, but does adding sodium chloride to a scum bag of urine make it drudge at a high temperature? Being a person that cooks frequently at home, I precious to test the debated idea that adding tabular array salt to my piss give make it boil faster. genius of my friends says it does raise the temperature and therefore cooks it faster. My other friend says it only helps it degustation better.Literature ReviewTable salt is often added to water supply in front the simmering process in hopes that the water will boil faster. It has been argued that the simmering temperature difference is insignificant with a small pot of water. However, when adding salt to large amounts of water, the change is more than noniceable.Southwest Research Institute states that the heat power of salt water is less than that of pure water, which means that it takes less dynamism to raise the 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, front is how more heat you put into the pot, second is how fast the temperature rises and third is the turn mind of the liquid (Southwest Research Institute, 2014).salinity elevates the boiling temperature of water victimization a process known as boiling point elevation. With water macrocosm a known solvent 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 saltiness on the Boiling Temperature of body of water). Experimental Design StepsWater will be boiled four different times as follows1.2 cups of distilled water are added to a 2 dry quart cooking pota. initiative lead add NO salt this is the controlb. Second run add 1 Tablespoon of table salt Trial 1c. Third run add 1 Tablespoon of table salt Trial 2d.Fourth run add 1 Tablespoon of table salt Trial 32. For individually r un, bring water to boil3. For each run, record the highest temperature reading of the boiling water4. After first through third runs, allow pot and burner to cool5. Wash pot after each run to clean salt residue argumentationA typical recipe will call for a flutter of salt in the water. The articles I read made 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, because when adding a dash, you will not have the same measurement of salt to each pot of water as you would when measuring the salt with a tablespoon. In order to thin error, so I used three struggles.Sequence of EventsDuring each trial I will be measuring the temperature of the water with a thermometer. formerly it reaches its highest temperature, I will record it in my data table. This will be the process for each trial.Tools, Technologies, and Measu rement UnitsTable SaltDistilled Water2 Quart Cooking PotPint measuring cupteaspoon and tablespoon measuring spoonsThermometer (Degrees Fahrenheit)Stirring spoonStove top burner (electric)Variables commutative Variable Amount of salt added to the waterDependent Variable Temperature at which the water boilsControlled Variables Temperature of stove setting, pot, type of water, brand of salt, amount of water, thermometerThreat reduction to Internal ValidityBy 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 passion unit, pot, and thermometer each time to get more valid results.HypothesisThe scheme of this examine 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 Run 121 4.9F1 Tablespoon Salt Run 2215.3F1 Tablespoon Salt Run 3215.1FAs predicted, adding salt to water does raise the boiling temperature of the water, even 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 all-important(a) to measure both the water and salt unblemishedly to ensure accurate 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 rumple the two ingredients together. The saucepan was then 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 215.1 degrees Fahrenheit, while the temperature of the control was 212.7 deg rees Fahrenheit. This was a difference of 2.4 degrees. shoemakers lastConfirmation 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 gaunt 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 come upon to helping you keep your results reliable and valid. You only need one individual variable. If you have more than one, you wont know which one is in truth affecting your results, it will also be harder to measure. Making as galore(postnominal) variables as possible constant will help increase the dependableness of the experiment.ReplicationBy following 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 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.).
