Modulated differential scanning calorimetry (MDSC) is right choice for measuring specific heat. Take a few measurements, then calculate stadard deviation and further calcualte relative standard error. If these values are less than 10%, we can say uncertainty is with the targetted values.

Hello Marllory,

You could have a look at this article to see how the uncertainty is calculated:

Article Uncertainty of heat capacity measurements with differential ...

Best regards.

Bashar Abdulrahman Mahmoud thank you. I'll keep it in mind

Nelaturi V Raghavaiah Some times sometimes it is not possible to take many measurements to do this procedure

Dear madam,

You can also compare the experimental value with theoretical or calculated or previously carried one. Otherwise, u recalibrate all the instruments and check the repeatability. See this value with in 1% error to get accurate experimental values.

Hi Marllory,

You could also have a look at the supporting information of this article to see how the uncertainty has been calculated: Article Acoustic Method for Determination of the Thermal Properties ...

Its all in section B.PROPAGATION OF EXPERIMENTAL ERRORS.
