Question
Had a lab session about how temperature relates thermocouple voltage, resisstance and lenght of alcohol in uncalibrated thermometer. Experiment was conducted by taking readings of thermomers at boiling and freezing points of water in beaker. Are they all directly proportional? What are the sources of error? Had a lab session about how temperature relates thermocouple voltage, resisstance and lenght of alcohol in uncalibrated thermometer. Experiment was conducted by taking readings of thermomers at boiling and freezing points of water in beaker. Are they all directly proportional? What are the sources of error?Explanation / Answer
Yes they are all prapotional to your experiment
Source of error
1. Selecting wrong type of thermocouple leads to an error in your experiment
2.the connection to the extension wire is also leads to an error
3. Cold junction compensation
4. Parallax errors while measuring voltmeter.
