1. What was the temperature alteration for the H2O in the calorimeter ( ?Twater ) ? 3°C
2. What was the temperature alteration for the metal sample ( ?Tmetal ) ? Assume the intial temperature of the metal was the same as the temperature of the H2O it was boiled in. 70°C
3. What was the specific heat of H2O in J/g°C?
4. 186 J/g°C
4. Using the undermentioned equation. your replies to inquiries 1-3. and your informations tabular array. find the specific heat of the metal sample you tested.
5. Identify you metal utilizing the list of specific heat values provided. The metal that was identified was Zinc.
6. Calculate the per centum mistake in the particular heat value that you determined by experimentation.
The intent of this experiment was to find the individuality of a enigma metal by happening the specific heat of the metal and comparing it to a list of specific heat values for different metals. Before get downing the lab and during the lab. the mass of the metal sample and H2O sample was taken. This information was subsequently used to assist find the specific heat of the enigma metal. The temperature of the boiling H2O. the temperature of the H2O in the calorimeter without the metal. and the temperature of the H2O and metal in the calorimeter were besides collected to assist find the enigma metal. After this. the temperature alterations for the H2O in the calorimeter and the metal sample were collected. After all the information was gathered. an equation was used to happen the specific heat of the enigma metal and find its true individuality. The deliberate specific heat of the metal was 0. 231 J/g°C. Even though this was close to the specific heat of Cadmium. the existent metal was Zinc. which had a specific heat of 0. 390 J/g°C. The intent of the lab was met. but non really good. There was a per centum mistake of 40 % . which is laughably high.
Many things could’ve gone incorrect in the lab such as reading the thermometer incorrect. misestimating the specific heat of the “mystery” metal. or non following the process. One thing that could’ve gone incorrect is the possibility of reading the thermometer incorrect. Reading the thermometer incorrect could’ve resulted in the failure of the full lab. Another possible mistake was misestimating the specific heat. This is really plausible and easy to accomplish. It is no surprise if it happened during the lab. One concluding mistake could’ve been non following the process. Not following the process could’ve easy messed up the full lab. Following waies is a really important portion of any lab.
Despite these mistakes. there are ways to repair them. One solution is to utilize a digital thermometer alternatively. This would extinguish the possibility of reading the thermometer incorrect. Another solution is to explicate the equation more clearly. Making the equation every bit clear as possible to anyone who may utilize it could decidedly about wholly wipe out the misinterpretation of an equation. One last solution is to read the process exhaustively multiple times before get downing the lab. This would guarantee that no way has been skipped or skimmed. and the lab will run swimmingly.
