Question

what effect will a 1.0 degree celcius error (all temperature readings are 1.0 degree celcius greater than the actual value) in determining absolute 0 K? Justify your answer.

Answer 1

1-degree celsius error implies that there is an error of 1 Kelvin in the temperature readings. Hence on determining 0K the temperature will always remain 1 Kelvin more and the reading would show 1 K always. This error is very big for the experiment because achieving Absolute zero is impossible and we can only go down to some very low millikelvins at the best, and therefore an error of 1 K would be very big and would cause a very big offset from the actually required temperature for the particular experiment.
