Round 9: Tossup 8

Measurements of this quantity are interpolated using 9-, 12-, and 15-degree polynomials in a calibration standard defined by 14 fixed points. This quantity is determined precisely from a platinum wire enclosed in a quartz or ceramic sheath calibrated to the ITS-90 standard. A mixture of chromel and constantan is used (10[1])to determine this quantity using electrical resistivity. (-5[1])This quantity is inferred from the curvature of a bimetallic strip. (10[1]-5[1])In 2019, the SI unit for this quantity was redefined in terms of Boltzmann’s constant. (-5[2])The spectrum of blackbody emission depends only on this quantity. The zeroth law of thermodynamics provides the theoretical justification for devices that measure this quantity consisting (10[1])of ethanol in (10[1])a glass bulb. (10[1])For 10 points, name this quantity measured in kelvins. (10[1]) (10[2])■END■
