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