  <dc:description>&lt;p&gt;The heat capacities of Calorimetry Conference copper and of muscovite, pyrophyllite, and illite were measured between 15 and 375 K using an adiabatic calorimeter. Tables of the thermodynamic functions &lt;i&gt;C°&lt;sub&gt;p&lt;/sub&gt;&lt;/i&gt;.(&lt;i&gt;H°&lt;sub&gt;T&lt;/sub&gt;&lt;/i&gt; —&lt;i&gt;H°&lt;sub&gt;O&lt;/sub&gt;&lt;/i&gt;)&lt;i&gt;/T&lt;/i&gt;, (&lt;i&gt;G°&lt;sub&gt;T&lt;/sub&gt; —H°&lt;sub&gt;O&lt;/sub&gt;&lt;/i&gt;)&lt;i&gt;/T&lt;/i&gt;, and &lt;i&gt;S°&lt;sub&gt;T&lt;/sub&gt; —S°&lt;sub&gt;O&lt;/sub&gt;&lt;/i&gt; are presented for these phases at integral temperatures from 0 to. 370 K. At 298.15 K (25.0°C), &lt;i&gt;S°&lt;sub&gt;T&lt;/sub&gt; —S°&lt;sub&gt;O&lt;/sub&gt;&lt;/i&gt; is 33.12±0.06, 287.7±0.6, 239.4±0.4, and 1,104.2±0.6 J/(mol•K) for copper, muscovite, pyrophyllite, and illite, respectively. The operation of a semiautomatic data-acquisition system for calorimetric measurements at low temperatures is also described, together with a description of a miniature calorimeter having a novel closure seal.&lt;/p&gt;</dc:description>
