Round 11: 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 to determine this quantity using electrical resistivity. (-5[1])This quantity is inferred from the curvature of a bimetallic strip. In 2019, (10[3])the SI unit for this quantity was redefined in terms of Boltzmann’s (10[1])constant. (10[2]-5[1])The spectrum of blackbody emission depends only on this quantity. The zeroth law (10[1])of thermodynamics (10[2])provides the theoretical justification for devices that measure this quantity consisting of ethanol in a glass bulb. For 10 (10[1])points, name this quantity measured in kelvins. (10[2])■END■
