Physics LabShc of Water Free Essays

The result I will get as the SSH of water will not be exactly the same as the literature value, but ill be a very close figure to the literature value of the SSH of water as there will be some limitations to our experiment. The experimental result 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. We will write a custom essay sample on Physics LabShc of Water or any similar topic only for you Order Now 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 wasn’t 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 random and systematic errors that I came across. The main errors I identified were the following: When transferring the iron block into the calorimeter some heat was lost to the surroundings as the block was out in the open. The simple calorimeter we used was made from a copper can, and when the water and iron block were boiling the can was nearby, and since it’s a metal and metals are conductors of heat it possibly has gained heat from the Bunsen burner. Therefore, the temperature difference of the mixture, as a result, could have been made smaller by reason of heat being gained by the calorimeter. The cover of the calorimeter wasn’t fully closed, leaving the water inside exposed and vulnerable to evaporation, which could lead to the loss of mass of the water and also 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 Improvements Weakness – Improvement Calorimeter gaining heat from the Bunsen burner close by because of the material it’s made from Introduce a calorimeter that is made from a substance that doesn’t let outside intrusions affect it. The cover of the calorimeter not fully closing Use a lid that fits the copper can so that the water inside of it isn’t 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 characterist ics of an insulator as the test material (metal block) How to cite Physics LabShc of Water, Papers
