Physics LabShc of Water

The w dyspeptic I will get as the SSH of water will non be exactly the same as the lit respect, just ill be a very close figure to the literature value of the SSH of water as there will be approximately limitations to our experiment. The data-based will I acquired was 4119. 54 Jag-1 K-1, lower than I expected, while the literature value is 4200 Jag-K-1 this shows that the experiment was carried out correctly, but not perfectly. There is a 2% error in my result when compared to the literature value. The errors can be due to the fact that the experiment wasnt orchestrated under professional conditions in a top-notch lab. Thus, one can without a doubt conclude by saying that the experiment faced mom errors while it was being conducted, but still arrived at the area of the expected result.Evaluation The experiment was conducted well, despite the stochastic and systematic errors that I came across. The main errors I identified were the following When transferring the squeeze choc k up into the calorimeter some change was lost to the surroundings as the block was out in the open. The simple calorimeter we used was made from a bullshit can, and when the water and iron block were boiling the can was nearby, and since its a metal and metals are conductors of heating it possibly has gained heat from the Bunsen burner. Therefore, the temperature difference of the mixture, as a result, could birth been made smaller by reason of heat being gained by the calorimeter.The cover of the calorimeter wasnt fully closed, leaving the water inside(a) exposed and vulnerable to evaporation, which could lead to the loss of mass of the water and as well as cause the water to lose or gain heat from the surroundings, which could have been the reason I got results lower than what I expected, even though it would result in a very minute difference Suggestions for gains Weakness Improvement Calorimeter gaining heat from the Bunsen burner close by because of the framework its made from instal a calorimeter that is made from a substance that doesnt let external intrusions stir it. The cover of the calorimeter not fully closing Use a chapeau that fits the copper can so that the water inside of it isnt exposed to outside air Heat lost to surroundings when transferring ten test material (metal Deadlock) Into ten calorimeter Put forward a scheme whereby less heat is lost to the surroundings or use a metal that has some characteristics of an insulator as the test material (metal block)
