Distinguishing coefficient
WebStatistical software reports that r2 = 100% and r = 1.000. Both measures tell us that there is a perfect linear relationship between temperature in degrees Celsius and temperature in degrees Fahrenheit. We know that the relationship is perfect, namely that Fahreheit = 32 + 1.8 × Celsius. It should be no surprise then that r2 tells us that 100% ... WebIn the methodology section they refers to the thermal expansion coefficient of water as. a = 1.6 × 10 − 5 × 9.6 × 10 − 6 × T. where T is the water temperature in ∘ C. This is valid for temperature in the range of 20 − 30 ∘ C. Can anyone point me to a cite-able paper that calculates the thermal expansion coefficient as a function ...
