Calorimeter, Metals
Abstract – This report is about an experiment on determining certain Specific Heats of certain different solids through the method of using mixtures. The experiment was conducted was focused mainly on how the specific heat was to be determined through the observation of the transfer of energy from one substance to the other. The data were gathered through the measurement of the temperature using a thermometer and through the use of a calorimeter to minimize unwanted loss of heat energy. Results from the experiment were used to verify the theory wherein heat energy is transferred from one body to another due to the difference in their temperatures.

Methodology
Preliminary Steps
Before starting the experiment, the materials were checked such as the calorimeters were completely dry, the scale was calibrated, the metal samples, aluminum, copper, and lead, were completely dry, there was boiling water and tap water (temperature was recorded), and the thermometers were at room temperature. Fig. 2 Illustration of a Calorimeter and a Thermometer Actual Experiment
We initiate the experiment by measuring the mass of the dry calorimeter. We then measure the individual masses of each of the 3 metal samples. After which, we then fill the calorimeter with an appropriate amount of water which can fully submerge the sample without it having contact with the bottom of the calorimeter. We also fill the steam generator with water until it is half-way full. We then measure and record the temperature of the calorimeter with tap water. We then attach a string to the sample and place it into the boiling water for at least 4 minutes, making sure it does not make contact with the bottom of the steam generator. We then take the sample out of the water and immediately wipe it thoroughly, after which it is placed in the calorimeter with tap water. We then stir the water around the sample in order to quickly attain thermal equilibrium. We record the final temperature once thermal equilibrium of water and the sample together is attained. We then repeat the said steps but then with the other

775 Words | 4 PagesIn the first part of the experiment, Part A, the standard solutions were prepared. As a whole, the experiment was conducted by four people, however, for Part A, the group was split in two to prepare the two different solutions. Calibrations curves were created for the standard solutions of both Red 40 and Blue 1. Each solution was treated with a serial 2-fold dilution to gain different concentrations of each solution.

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.

939 Words | 4 PagesThe beginning temperature of the substances used was between 21∘C and 22∘C. By 90 seconds into the experiment the temperature was at 72∘C. Immediately after 90 seconds the experiment had ended because then the temperature of the mixed substance was decreasing to go back to room temperature where it started. The final temperature that my group took was 33∘C at 8 minutes and 12 seconds.

Cold Water Lab
630 Words | 3 PagesIntroduction The intent of this experiment is to understand how hot and cold water interact with each other by combining clear hot water and black ice cold water. I hope to learn more about how hot and cold water interact with each other. As of now, I know that cold water is denser than hot water. Knowing this I formed my hypothesis.
Molar Mass Of Unknown # 43 Using The Derived Freezing Point Depression
1294 Words | 6 PagesModifications of this procedure include the use of hot plates instead of Bunsen burners, and heating t-butyl alcohol to 60-65 ℃ instead of 50 ℃. Other modifications include the use of weighing boats to measure an amount of unknown instead of weighing paper, and completing one run of unknown 2 instead of two runs of unknown 2. Summary of
Mass And Mole Relationships In A Chemical Reaction
949 Words | 4 PagesThe items that were massed were the evaporating dish, watch glass, and NaCO3. The materials were massed once before and once after being heated in the drying oven. The mass of the evaporating Dish before was 46.57 g; while after being heating was 60.15 g. The mass of the watch glass before was 57.97 g and after was 48.75g. There were two masses taken for the substance NaHCO3- one with the evaporating dish and one without, subtracted out after the lab was concluded. The mass of the substance with the dish was 48.79 g before and 62.33 g after; meanwhile, the mass of the substance without the dish was 2.22 g before and 2.18 g after. The mass of the NaHCO3 had changed after the reaction occurred along with after it was placed on the hot plate and being in the drying oven.

I did not grease the screw, so as I was shaking the mixture, solids were forming around the screwpart of the separatory funnel. 2. When adding 5.0 mL of NaOH to the unknown mixture and shaking it for about 30 seconds, layers had formed.

Aquatic Snail Case Study
174 Words | 1 PagesWe also collected quantitative data for the aquatic chamber. We collected how much dissolved oxygen in the water, the pH of the water, and the water’s temperature. It was Billy’s job to collect the temperature of the water and how much dissolved oxygen there was in the water. To find the temperature of the water, Billy used a temperature probe that could be put in the water and placed it into the water. Billy then used a special probe that measures the dissolved oxygen and placed it into the water to get the amount of the dissolved oxygen.
Water Hydration Lab Report
603 Words | 3 PagesIn this experiment, the amount of water lost in the 0.99 gram sample of hydrated salt was 0.35 grams, meaning that 35.4% of the salt’s mass was water. The unknown salt’s percent water is closest to that of Copper (II) Sulfate Pentahydrate, or CuSO4 ⋅ 5H2O. The percent error from the accepted percent water in CuSO4 ⋅ 5H2O is 1.67%, since the calculated value came out to be 0.6 less than the accepted value of 36.0%.This lab may have had some issues or sources of error, including the possibility of insufficient heating, meaning that some water may not have evaporated, that the scale was uncalibrated, or that the evaporating dish was still hot while being measured. This would have resulted in convection currents pushing up on the plate and making it seem lighter by lifting it up
