Packet M: 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 (-5[1])using electrical resistivity. (-5[3])This quantity is inferred from the curvature of a bimetallic strip. (10[3]-5[3])In 2019, (10[4]-5[1])the (10[1])SI (10[1])unit (10[1])for this quantity was redefined (-5[2])in terms of Boltzmann’s (10[1])constant. (10[4]-5[3])The spectrum of blackbody emission depends only on this (10[1])quantity. (10[2]-5[1])The zeroth law (10[2])of thermodynamics (10[3])provides (10[1])the theoretical justification for devices that measure this quantity (10[1])consisting (10[2])of (10[1])ethanol in (10[1])a glass bulb. (10[2])For 10 (10[1])points, name this quantity measured in kelvins. (10[1]) (10[15])■END■
