Tap Water Temperature Lab Report

719 Words3 Pages

Statement of Problem: Using a thermometer with graduations above 40ºC covered, construct an experiment to find the temperature of the water found in a coffee pot which simulates a water heater that can be heated to 55ºC. Hypothesis: If the temperature of 50mL of tap water is found and then mixed with 25mL of hot water, then the temperature of the hot water can be determined because by finding the final(mixture of hot/tap water) and initial(tap water) temperatures, the experimenter can discover the original temperature the hot water was before it was mixed with the tap water. Experiment: Procedure: Fill a graduated cylinder with 60mL of tap water Pour the measured 60mL of tap water into one styrofoam cup and let it sit for two minutes …show more content…

After two minutes, determine the temperature of the tap water, this will be the initial temperature in the equation Write out constants for the equation -q(exo)=q(endo) Fill the same graduated cylinder this time with 40mL of tap water Pour the 30mL of tap water into a second styrofoam cup and mark with a pencil the water level in the cup Pour the 30mL of tap water out and fill the same styrofoam cup with hot water using the pencil mark as a guide—be careful not to spill hot water or touch hot surfaces Quickly mix the 30mL of hot water to the 60mL of tap water together in a third styrofoam cup Measure the temperature of the combined hot/tap water mixture, this will be the final temperature in the equation Calculate the equation with the temperatures found with the thermometer Independent Variable: ratio of water samples in mL Dependent Variable: The temperature of the hot water Controlled: using the same hot water (coffee pot), styrofoam cups, and thermometer …show more content…

Using these new measurements will give the same outcome as the 50mL of tap water and 25mL of hot water as stated in the hypothesis. However, we redid our experiment and tested the water ratio with 60mL to 30mL and found the same answer of 65ºC. The data shows both water ratios do in fact give the same result making this procedure accurate and can allow the experimenter to find the right temperature of the hot water. My lab partner and I learned that by finding the initial and final water temperatures within our experiment, we were allowed to use a simple equation which could get us our answer. We figured out how to use the equation -q(exo)=q(endo) more efficiently and were able to understand its function

The beaker with NaOH was placed on the hot plate and 3.75 grams of NaAlO2*5H2O was placed in the beaker. The temperature probe was placed in the beaker with the solution, not touching the bottom of the beaker. The solution was heated and stirred till the solution dissolved.

    The temperature probe was then quickly cooled to room temperature. When this was achieved, the hot water was immediately transferred into the calorimeter. This method of keeping the temperature probe cooled before measuring a new temperature was repeated throughout the entire experiment. Temperature data was collected for 180 s while swirling the temperature inside the calorimeter. The calorimeter still contained the warm water.

    One of the issues was pouring the water in the different test tubes at the same time, as only one member of the group poured in the water into the test tube at separate times. This is an issue as it makes the initial temperature for each of the test tubes lower than the recorded initial temperature (43 degrees Celsius) because the room temperature can cool down the water when the timer isn’t activated. It also affects the data as the temperature change for the first 3 minutes can’t be observed, so I can not know if the temperature for each of the test tubes decreased fast or slow from 0 to 3 minutes. This effect has great significance to making the data inaccurate, because the calculated temperature drop most likely is incorrect, meaning the evaluation of the hypothesis - that is based on the temperature drop - could be also wrong. Additionally, I can not observe an accurate reliable pattern between the different tests, because of the altered data.

    This heating and cooling was repeated until there was very little (less than 0.0010 grams) fluctuation in numbers. Vial one had a start weight of 14.7681 and an end weight of 15.4098, meaning the mass of the water was 0.4658. Vial 2 had a start weight of 14.7451 and an end weight of 15.3833, meaning the mass of the water in this sample was 0.4633. The mass of the water was found by subtracting the mass of the vial with the hydrate (the start weight) from the mass after the final heating (the final weight). To then find the percent water divide the water mass by the hydrate mass and multiply by 100 since the number is a percent.

  • Essay On The Effect Of Temperature On Osmosis

    1159 Words  | 5 Pages

    Exploration Title: Effect of Temperature on rate of Osmosis Submitted By: Abdulkarim Kamal Date Submitted: October 19th 2015 Subject: Biology HL Teacher: Mr. Nick   Aim: This is an investigation to determine the relation between temperature of a solution (sucrose) and the rate of osmosis Scientific Context: Osmosis is defined a passive transport process in which a fluid diffuses across a semi-permeable membrane, from an area of high solute concentration to an area of low solute concentration and vice-versa. There are various factors that could potentially influence the rate of osmosis; these factors include volume, concentration, and temperature. If all external factors that may interfere with rate of osmosis are controlled, the results will show equal amounts of fluid on both sides of the barrier (membrane); this is known as an “isotonic” state.
