Seebeck Effect

Post by lilymcbride07 »

I am getting confused on this step for the Seebeck Effect experiment

2)Look up the thermoelectric electrical potential difference for your observed room temperature for a Type K thermocouple in this Type K thermocouple data sheet. Note the value in your data table. Pay attention to the sign (negative or positive)!

Hello,

In the datasheet, the first column indicates the row's temperature in 10s. The following columns indicate the temperature in 1s.

If your room temperature is 25C, for example, look for the row starting with 20, and then look for the column with heading 5 which should be 1.000 mV.

Below is the section you need in the dataset. I highlighted the entry in bold. Formatting is not good in this reply. I encourage you to go back to the datasheet and look at it.

Hope this helps.

°C 0 1 2 3 4 5 6 7 8 9 10
Thermoelectric Voltage in mV
0 0.000 0.039 0.079 0.119 0.158 0.198 0.238 0.277 0.317 0.357 0.397
10 0.397 0.437 0.477 0.517 0.557 0.597 0.637 0.677 0.718 0.758 0.798
20 0.798 0.838 0.879 0.919 0.960 1.000 1.041 1.081 1.122 1.163 1.203
30 1.203 1.244 1.285 1.326 1.366 1.407 1.448 1.489 1.530 1.571 1.612
40 1.612 1.653 1.694 1.735 1.776 1.817 1.858 1.899 1.941 1.982 2.023

Thank you! I am now stuck on this step

6)Look up for which temperature a K thermocouple produces the thermoelectrical potential you just calculated using the Type K thermocouple data sheet. Write this temperature down in your data table.

i got the number 0.279 and that is not in the chart

Hello LilyMcBride07,

Thank you for your patience waiting for the expert who has been helping you. Expects are volunteers so might not be able to respond immediately to your follow-up questions.

The best way for the expert to see your follow-up question is to post your question in the same thread as for your original post.

And, Science Buddies does request that you only post a question once! As a moderator, I have removed your last post ... as you can see, that post is in the original thread, so the expect will see that.

Thank you again for your patience, and best of luck with your project!
